Announcing .NET Core 1.0

BinaryIdiot 10y ago
Interesting name choice considering they have already had a .Net 1.0. I mean I get it, I understand why they chose to make this more of a 1.0 release but for those already in the .Net ecosystem it seems a little confusing to me.
- malekpour 10y ago
  It could have been more confusing by bumping versions. They first tried ASP.NET 5 and ASP.NET MVC 6 and EF 7 and there was no simple migration path from older version. Now they are all Core 1.0
- recursive 10y ago
  Excuse me if this was already obvious, but the word "core" designates a new product line, starting from 1.0. Obviously, it's informed heavily from the old .net framework, but it's not backwards compatible with it.
  - BinaryIdiot 10y ago
    Sure it's obvious. Like I said I "get it" it's just core has always been a part of .Net just less directly referred to so my first thought was this was .Net 1.0's core until I started reading through the link. Overall I think it's a good move just a little confusing (unless I'm the only one) for those who have done .Net work before.
  - lmickh 10y ago
    This is just a personal view, but my first instinct when I read about product "CoolApp" and "CoolApp Core" would be to assume core is a subset of the first. Not a new and re-engineered product line. I could see why others might see .Net Core as a parallel product as opposed to a new one.

Does this represent some kind of change for .NET? Why is it called 1.0?
- enricosada 10y ago
  Because it's the first version of the xplat .NET (the .NET Core) supported by Microsoft (mono already does an amazing works as xplat, and have done that for years). It's not confusing if you work in .NET, the .NET Framework 1.0 was released in 2000..
- malekpour 10y ago
  They reset versioning to 1.0 by renaming .NET to .NET Core
  - FLGMwt 10y ago
    The full .NET framework (Windows only) will live on, currently at 4.6.2, I believe. ".NET Core" is the new open source, cross-platform subset of the full .NET framework.
    - insulanian 10y ago
      IMHO the full .NET is from today considered a legacy platform. I would compare the situation to WebForms / MVC - who does new projects with WebForms now?
      - oblio 10y ago
        As far as I remember the long term plan is to stack the remaining APIs from the full .NET on top of .NET Core. So Microsoft would have: .NET Core - base for everything. .NET - Windows specific bits, Xamarin - mobile specific bits.
- jsingleton 10y ago
  It's v1.0 of the "Core" open-source rewrite.

dogma1138 10y ago
I was really hoping for ARM support at least as far as RasPi goes for 1.0. But still very good news I personally love .Net it's nice to be able to use it cross platform without having to work specifically around mono.
- oblio 10y ago
  From what I see Samsung has been contributing on that front. They said in the announcement that Samsung has joined the Dotnet Foundation.
  - dogma1138 10y ago
    Yeah, the only problem with Samsung is that they most likely going to make builds for the Exynos based SOC which isn't that wide spread. The ARM ecosystem is quite fragmented and depending on how you build your software it's not as portable as one would assume. It's also not clear which instruction sets they are going to be aiming for Exynos started with ARMv7 + all the stuff that Samsung added to it, but the newer ships are ARMv8. The Raspberry Pi still uses ARMv6, 7 and 8 depending on the exact model with the newer RasPi compute, and Zero models still running the old BCM2835 ARMv6 CPU's. So I'm hoping for a more or less clean stock ARMv7 and ARMv8 builds for the .NET core coming out sooner rather than later, I also hope they'll release the X86 version to more platforms than Windows since running it on something like an Intel Edison which comes with a 32bit ATOM CPU will be quite cool. .NET is quite powerful and for my taste it's considerably better than Node.JS (I don't like Javascript, this isn't some technical observation just personal preference) but I do like C# and F# quite a bit and having the ability to run the same code across multiple platforms makes me excited for IOT/Embedded devices again especially considering that I don't have to work through some of the headaches that come with Mono (some pun indented).
    - oblio 10y ago
      Well, I imagine that if someone offers support for those platforms they won't say no. But they'd probably also need for stuff such as the CI chain.

gldev 10y ago
After so many years microsoft finally presenting their tools in a more moden way. Never been a huge fan of .NET but i can't deny is a great tool hopefully people try it out on more platforms.
- whatever_dude 10y ago
  I still can't shake the feeling that their naming is just confusing. I still am not sure what exactly is .NET and what's not.
  - gldev 10y ago
    Yes, that's a thing but at this point imagine just how much more confusion it could create if they change the name.
  - bigtones 10y ago
    .Net is 14 years old now - if you don't know what it is by now you're probably not ever going to know. It's a cross platform runtime and a group of programming languages that run on it, just like Java.
    - chinhodado 10y ago
      The general idea of .NET as a platform is easy to understand. The naming of .NET Core, .NET Framework, ASP.NET, etc. and the difference between them is not.
      - oblio 10y ago
        .NET Framework = the whole shebang, the full runtime including Windows-only bits. .NET Core = portable subset of .NET Framework. Therefore not entirely compatible with .NET Framework. ASP.NET Core = portable rewrite of ASP.NET. AFAIK not fully compatible with previous versions.

Documentation as a PDF (constantly updated): https://readthedocs.com/projects/aspnet-aspnet/downloads/pdf/latest/ https://readthedocs.com/projects/aspnet-aspnet/downloads/pdf... It's really just a copy of their informational web site content with articles by different authors, but still very conveniently combined into a single PDF useful for printing etc.

AndreyErmakov 10y ago
A bit unrelated, but I'm hoping to hear something soon about the future licensing model for the upcoming SQL Server on Linux. Do we get a free version without DB size / CPU / RAM limitations (but perhaps with some other restrictions) that smaller companies and startups can use in production? I'm planning to run my future ASP.NET MVC projects on Linux and very much would like to know if a better SQL Server Express / Community Edition is coming or do I need to move to PostgreSQL (which I have already started looking into).
- BrentOzar 10y ago
  Microsoft already announced the SQL Server on Linux licensing: https://blogs.technet.microsoft.com/dataplatforminsider/2016/03/15/data-driven-top-10/ https://blogs.technet.microsoft.com/dataplatforminsider/2016... "A customer who buys a SQL Server license (per-server or per-core) will be able to use it on Windows Server or Linux. This is just part of how we are enabling greater customer choice and meeting customers where they are." Same editions, same prices.
  - AndreyErmakov 10y ago
    Thanks for the information! Apparently I missed that in the news stream. Sad to hear about that though. I was hoping for a break. Will just have to continue reading that PostgreSQL book I've already started.
    - AndreyErmakov 10y ago
      Now that someone has downvoted me, I know it is the right choice and I must learn Postgres. Thanks for your support, folks.
      - sherjilozair 10y ago
        PostgreSQL is the right choice, no matter what.

I was expecting they would fix the Uri class on Unix (https://github.com/dotnet/corefx/issues/1745 https://github.com/dotnet/corefx/issues/1745) before releasing 1.0 :( Now I fear their backwards compatibility policies will prevent to fix it later. So much for crossplatformness...
- tacos 10y ago
  Way too many compatibility issues unaddressed by that PR to have a hope of getting anything changed there. Also it looks like what you (?) are trying to do could easily be solved with the Path.* and Directory.* path manipulation functions. No need to put a million apps at risk when you can wrap your call to Uri() with a three line helper.
  - knocte 10y ago
    3line helper? facepalm...
    - triangleman 10y ago
      Care to enlighten us?
    - recursive 10y ago
      How many lines would be acceptable? Your frustration is inscrutable.
- jsingleton 10y ago
  They've renamed some packages, so this might possibly be fixed in another one? I found the Ping class didn't work on any non-Windows OS, but it was fixed in a later package with a new name.
computerlab 10y ago
A couple months ago I installed .NET core on a Ubuntu virtual machine running on the Windows 10 hypervisor, and was able to get a MVC5 app running using Visual Studio Code. As someone who really loves Visual Studio (it made me expect a lot more from my tools) and C# (it made me expect a lot more from my languages), it was an exciting moment. I actually took a selfie with my monitor. It was still a little rough: the "getting started" instructions ONLY worked on Ubuntu 14.x and not Ubuntu 16.x, and my PR to the documentation pointing this out was nixed. (I notice they've since added a disclaimer: https://docs.asp.net/en/1.0.0-rc1/getting-started/installing-on-linux.html#installing-on-ubuntu-14-04 https://docs.asp.net/en/1.0.0-rc1/getting-started/installing...). I really hope to someday be able to build projects with React and a .NET core WebApi and be confident that my teammates will be able to get the project running on their macbooks without kms.
- jsingleton 10y ago
  MVC 6 is the version that works best with Core, although they don't really refer to it directly much any more. Both MVC 6 and Web API 2 are now part of Core. They're just packages like everything else.
  - computerlab 10y ago
    Good point, I meant MVC6. I confused the versions of ASP.NET 5 (which is now known as ASP.NET Core) and MVC6.
    - jsingleton 10y ago
      The naming is really confusing, but then naming things is hard. As Phil Karlton famously said: There are only two hard things in Computer Science: cache invalidation and naming things.
      - recursive 10y ago
        I don't know where it came from, but I've always preferred this variant: There are only two hard things in Computer Science: cache invalidation, naming things, and off-by-1 errors.

I'm receiving > “dotnet-dev-osx-x64.1.0.0-preview2-003121.pkg” can’t be opened because it is from an unidentified developer." I know full well how to get around this, but it makes me suspicious of what I've downloaded. Would Microsoft have truly missed this?
- jsingleton 10y ago
  It is annoying. The preview MSIs are signed but the preview PKGs are not. The last release was so maybe it just takes some time? BTW you can ctrl-click/right-click the installer package and select open to get the option to run it without fully disabling gatekeeper. [https://github.com/dotnet/cli/issues/3434 https://github.com/dotnet/cli/issues/3434]

I'd LOVE to see some Linux web/micro benchmarks... particularly against Java, Go, Node, Python.
- manigandham 10y ago
  The webstack is pretty fast, they're working on getting listed officially in the techempower rankings [1]. Here's an older article from Feb explaining more details. [2] 1. https://github.com/aspnet/benchmarks https://github.com/aspnet/benchmarks 2. http://web.ageofascent.com/asp-net-core-exeeds-1-15-million-requests-12-6-gbps/ http://web.ageofascent.com/asp-net-core-exeeds-1-15-million-...
- tacos 10y ago
  From the release notes: "We used industry benchmarks for web platforms on Linux as part of the release, including the TechEmpower Benchmarks. We’ve been sharing our findings as demonstrated in our own labs, starting several months ago. We’re hoping to see official numbers from TechEmpower soon after our release. Our lab runs show that ASP.NET Core is faster than some of our industry peers. We see throughput that is 8x better than Node.js and almost 3x better than Go, on the same hardware."
- e12e 10y ago
  They link to some benchmarks in the article: https://github.com/aspnet/benchmarks https://github.com/aspnet/benchmarks (they're a little hard to read on mobile, but I think the tl;dr is "plenty fast" (or to quote the article: "Our lab runs show that ASP.NET Core is faster than some of our industry peers. We see throughput that is 8x better than Node.js and almost 3x better than Go, on the same hardware. We’re also not done! These improvements are from the changes that we were able to get into the 1.0 product.")
- JustSomeNobody 10y ago
  Me too. Especially compared to raw servlets, not the normal 50 layers of inheritance, enterprise crap.
- 616c 10y ago
  Scott Hunter of MS did an interview not so long ago re .NET, Kestrel (the new libuv HTTP server they build), and their march to build up as a top contender for Tech Empower. http://dotnetrocks.com/?show=1291 http://dotnetrocks.com/?show=1291 They have a team who does it all for fun and has an impressive testing environment build out. Fascinating to listen to given today's new. I listened a few weeks ago myself. I have friends at work who liked C# and moved on to frontend. The fact they are so less interested in .NET now is amazing to me as I finally want them to teach me to use ... on Linux!? I never thought I would say that. Haha.

I don't see mention of FreeBSD anywhere in the .NET Core 1.0 announcements -- has official support for FreeBSD dropped or been postponed?
- Voloskaya 10y ago
  * FreeBSD is listed on CoreCLR GitHub repo (https://github.com/dotnet/coreclr https://github.com/dotnet/coreclr). See current build status here: http://dotnet-ci.cloudapp.net/job/dotnet_coreclr/job/master/job/release_freebsd/ http://dotnet-ci.cloudapp.net/job/dotnet_coreclr/job/master/... * Also, see doc here (last updated in feb though): https://github.com/dotnet/coreclr/blob/master/Documentation/building/freebsd-instructions.md https://github.com/dotnet/coreclr/blob/master/Documentation/... * Laslty, FreeBSD arrived on azure last week, so it would be quite surprising if support was dropped.
  - montyedwards 10y ago
    I understand, but none of those links are the .NET Core 1.0 release announcements. And the download page for .NET Core 1.0 doesn't mention FreeBSD at https://www.microsoft.com/net/download#core https://www.microsoft.com/net/download#core

Do we officially have better-than-Java on all platforms now?
- interdrift 10y ago
  Looks like it.
- 16bytes 10y ago
  Language and tooling wise? Yes, or very close to it. There's a lot to be said about the huge amount of value in the main maven repository vs. what's in nuget. Java's decade long head start in that area doesn't seem so huge when you look at what the node.js community has put together in only a few years. If you were considering .net on a new project, however, I would probably recommend comparing something like Scala. Scala has the benefits of being a "modern" language like C# with the full support of all or nearly all of the existing JVM projects. That being said, there are a growing number of reasons to choose .net on non-windows platforms.
  - oblio 10y ago
    I'd argue that it will be a while for Nuget to catch up. When I go on Maven Central I expect every library to be cross platform except for those marked as platform dependent. For Nuget... all bets are off for now. It's the exact opposite, I assume that things are not portable or at least have not been tested on say, Linux.
  - rbanffy 10y ago
    > Java's decade long head start in that area doesn't seem so huge when you look at what the node.js community has put together in only a few years. It's easier to follow than to blaze a path. We have learned from Java and can, hopefully, avoid those pains.
- PopsiclePete 10y ago
  Yeah but so what. If the "best" language always won, why isn't the entire world running on Haskell and Rust or whatever? Java's eco-system is ginormous and it's deeply entrenched as the "corporate stack" in non-MS shops, with more than 15 years of history. I'm afraid this is just too late to make a big dent. C# is nicer than Java, but not that much nicer to warrant switching over or rewriting your stuff in a very immature eco-system. Maybe they're hoping to capture some of that elusive start-up market- and mind-share? That one is already pretty hostile towards MS... Either way, this is a good thing, I just wish they had done this in 2005 or so.
enricosada 10y ago
F# doesnt work ootb with sdk preview2. Work ok with preview1 of SDK (win/ubuntu/osx/docker), but preview2 has a bug, the fix is in progress ( ref https://github.com/dotnet/netcorecli-fsc/issues/12 https://github.com/dotnet/netcorecli-fsc/issues/12 ) and will be published a nuget package with fix soon.
- acangiano 10y ago
  You reported the issue 11 days ago. I'm surprised they just announced it with such a basic use case being broken. It doesn't bode well for F# as a first class citizen in their ecosystem.
  - ubertaco 10y ago
    Seconded. I saw the announcement and immediately went to grab the docker image and give it a shot with F# via "dotnet new -l F#" and go. It restored and built, but didn't run. So v1.0 is broken, I guess?
    - Eyas 10y ago
      I don't think so. It means that the tooling is broken, which is not at 1.0 yet (still in `preview2` I believe).
      - enricosada 10y ago
        Exacly, the preview2 of the sdk, atm, is broken for f#. Not the .net core, that's ok. new console/lib templates are going to be published (with the fixed fsharp compiler/library package), that's all.
        ubertaco 10y ago
        Still a little odd for a release announcement. It feels disingenuous to only afterwards make the fine-grained distinction that yes the libraries are technically v1, but the tooling is still in preview. Kinda like announcing your new line of cars is ready for purchase today! Except that down in the fine print you might find out that the engine is ready to go, but the steering wheel, headlights, dashboard, and pedals are all still in development and so it's justifiable that they're broken.
SoapSeller 10y ago
It's fascinating how Microsoft's marketing moved from ".Net - One platform with multiple languages" to "This is .Net - here some samples in C#"(without mentioning C# by name anywhere in the page). I think that .Net would be much better if they had this kind of focus in dev side from the start. *Hides from the f# mafia.

I don't understand, why does the package name for Linux say preview2? apt-get install dotnet-dev-1.0.0-preview2-003121 Isn't this the final release?
- jsingleton 10y ago
  The preview refers to the tooling (CLI, VS etc.) [https://github.com/aspnet/home/wiki/roadmap#schedule https://github.com/aspnet/home/wiki/roadmap#schedule]
- michaelmior 10y ago
  Even if this isn't the final release, I'm confused why they would include version numbers in the package name at all. One of the reasons of having a package manager in the first place is to avoid things like this.

    I have a Slackware server, I have tried a few times to get started with .net core but I've given up every time because it's just so unclear what I have to do and where to find everything. Maybe if I have Debian or Fedora it's easy, but I don't, and I just cannot seem to find a simple article that says: here download this, run that, and you're good to go. So I guess I'll try again in a few months.
daveguy 10y ago
FYI, from the announcement. Probably the most important part at the end, italicized by me. Also note (elsewhere) that licenses are MIT and Apache2: .NET Core Tools Telemetry The .NET Core tools include a telemetry feature so that we can collect usage information about the .NET Core Tools. It’s important that we understand how the tools are being used so that we can improve them. Part of the reason the tools are in Preview is that we don’t have enough information on the way that they will be used. The telemetry is only in the tools and does not affect your app. Behavior The telemetry feature is on by default. The data collected is anonymous in nature and will be published in an aggregated form for use by both Microsoft and community engineers under a Creative Commons license. You can opt-out of the telemetry feature by setting an environment variable DOTNET_CLI_TELEMETRY_OPTOUT (e.g. export on OS X/Linux, set on Windows) to true (e.g. “true”, 1). Doing this will stop the collection process from running. Data Points The feature collects the following pieces of data: The command being used (e.g. “build”, “restore”) The ExitCode of the command For test projects, the test runner being used The timestamp of invocation The framework used Whether runtime IDs are present in the “runtimes” node The CLI version being used The feature will not collect any personal data, such as usernames or emails. It will not scan your code and not extract any project-level data that can be considered sensitive, such as name, repo or author (if you set those in your project.json). We want to know how the tools are used, not what you are using the tools to build. If you find sensitive data being collected, that’s a bug. Please file an issue and it will be fixed.

Good news! Now time for all the library and framework authors to add support for .NET Core. I know a lot of people were waiting for RTM before starting this, considering the massive changes between RC1 and RC2. I've started a support matrix project at https://anclafs.com https://anclafs.com. Feel free to file an issue or send a PR on GitHub.
- enricosada 10y ago
  the asp.net core changed a lot between rc1 and rc2 (because moved to .net sdk instead of dnx). The normal libraries or console app not too much
  - jsingleton 10y ago
    It depends on if you want to run ASP.NET Core on .NET Framework 4.6 or on .NET Core 1.0. It's not just the SDK that is new, Core console apps are pretty recent too, as previously it was mainly for web apps.
- dewiz 10y ago
  You're missing akka.net there
  - jsingleton 10y ago

Does Microsoft have some diagram or something that shows how all the .NET things fit together (on Linux)? The C# development I've done was... fine, but that was seven years ago and it's like Java in the sense that it's an amazingly complex thing to grasp and keep up with. Understanding how everything is layered is pretty complicated at this point.

Presumably the .NET announcements were pre-scheduled, so if there is any connection between these posts, it must go the other way. But I don't believe there is.

Does this still use mono's jit and GC on mac and linux? Last I checked mono's GC is conservative and the jit isn't as good as the .NET one.
- mellinoe 10y ago
  It does not; it uses the same JIT and GC as the Windows version of .NET Core, and the code is also shared with the (full) .NET Framework that ships inside Windows. Actually, this has always been the case for .NET Core, but you may be thinking of our older preview versions which gave you the option to run your app entirely on mono. (I work on .NET at Microsoft)

If I'm an experienced Python developer who develops a lot of websites and APIs using Django or Flask and SQLAlchemy, is there any reason to try this stuff? C# is a great language, but what about the libraries? What replaces Flask? What replaces SQLAlchemy? How do I deploy? Looking for some practical reasons to invest time on this if Windows development is not in my roadmap.
- sakopov 10y ago
  Flask - Nancy SqlAlchemy - EntityFramework, nHibernate Deployment - AppVeyor (cloud), TeamCity/OctopusDeploy (self-hosted) Having said that, there is probably very little reason unless you're just doing it out of pure interest.

  No. If you really want a high performance Windows friendly server software, try Java. But honestly I would not use .net for anything past excel plugins.
- oblio 10y ago
  Well, besides libraries, performance. .NET supports proper multithreading (no GIL) and it is also much faster than CPython. If IronPython gets ported to .NET Core (maybe it already has, I don't know), then you'd get those benefits for free.

I've mixed feelings about this release, because it seems a bit early to me. Some fundamentals will change soon (project.json replacement) and I am still not able to get debugging to work in VS Code on OSX. The whole situation in the .NET Core space was very confusing for the last months and this trend seems to continue. This is sad, because I'd love to code in C# on any platform and that things would just work as advertised on the website. Edit: Debugging works now for me, after the .NET Core Debugger was automatically installed in the background!

  - mattmanser 10y ago
    I also think they've made a terrible decision, the first-class support for DI is a bad direction which has made many simple concepts like config settings into absolute farces that take 5 lines of code. It's code "purity" over usability. It's putting the core dev team's principles over their customers actual need, completely violating KISS, DRY and YAGNI. DI really is our generation's factories. I'm already seeing projects written by people who don't understand it making utter nightmare spagetti code, worse than any code I've ever seen. It's nasty scaffolding code which is a symptom of limitations of the language, definitely not code anyone should ever actually be wasting time writing. Instead of recognising it's a flash in the pan, the core team have embraced it and are trying to force it down everyone's necks, and a lot programmers simply don't get it and are making an utter mess instead.

  I don't know of any green threads in .NET -- at least, not built in. However, .NET does have a built-in thread pooling / task execution service. You generally interface via `System.Threading.Tasks.Task`[0], which has static `Run` functions, or use the `Factory` property to get the underlying `TaskFactory` for more fun. Since the executors are pooled, the creation costs will be amortized over your program's lifetime. Then there's `async`/`await`[1], which is built on top of tasks.

    I remember that a long time ago, .NET threading was implemented in such a way that it should, in theory, support Win32 fibers. It's why all the low-level .NET APIs don't use the OS thread IDs, but instead have their own IDs, and require explicit mapping. I believe that it was abandoned as a supported scenario a while ago, though. But you can still see artifacts of that in the docs, e.g.: https://msdn.microsoft.com/en-us/library/system.threading.thread.managedthreadid(v=vs.110).aspx https://msdn.microsoft.com/en-us/library/system.threading.th... "The value of the ManagedThreadId property does not vary over time, even if unmanaged code that hosts the common language runtime implements the thread as a fiber."

hackaflocka 10y ago
Is there a primer somewhere that explains simply what the difference and dependence is between .NET (core, foundation), ASP.NET (core, foundation), Xamarin, Visual Studio (in all it's different flavors including VS.NET etc.) and Visual Studio Code? I tried Wikipedia, and Microsoft's own homepages for each, and am even more confused. I'm a hierarchical thinker, and a hierarchical tree explaining the above would be very very helpful. Disclaimer: I haven't downloaded any of these yet. I usually don't until I've understood something. Bonus question: If I want to develop websites and electron apps using: HTML, CSS, Javascript and PHP, what's the minimum set of technologies (or whatever it is that Microsoft is calling them these days) I will need?
- oblio 10y ago
  Dotnet Foundation = NGO that manages various legal and org things for .NET. Think FSF for GNU. .NET Core = cross platform software development platform. Includes a VM, compiler, tons of libraries. ASP.NET Core = HTTP server + server side .NET libraries. There is no ASP.NET Foundation, it's all part of the Dotnet Foundation. Xamarin = .NET libraries for mobile development. Wraps Android/iOS native libraries. Visual Studio = native Windows IDE for .NET and other languages. Visual Studio Code = portable, Electron/HTML 5 IDE for Javascript/Typescript and other languages. You probably want Visual Studio Code for HTML/PHP. But you should check out .NET Core, it can replace PHP. By the way, if it works, it works, but I find it better to research and do at the same time. Downloading only after you've understood the org chart seems a bit too radical for me :)
  - hackaflocka 10y ago
    Thanks. Very helpful. Last 2 Qs: is Framework different from Core? And how does Windows Presentation Foundation fit in all this?
    - oblio 10y ago
      .NET Framework is the old .NET Framework. It's basically the entire shebang, tied to Windows: VM, class libraries, etc. .NET Core is as the name says, just the "core" of the .NET Framework, the part that's cross platform. However, I'm not sure that at this point the code's common, I believe at least a part of it has been reimplemented. I think that in the future .NET Framework will be based on .NET Core. Therefore .NET Framework will be .NET Core + Windows specific bits. WPF is the fancy name for a .NET UI toolkit for Windows, basically. Think of it as a Windows-only GTK.
eperfa 10y ago
I might be missing something here, but does this mean that .NET Framework and .NET Core have diverged, and you need to take extra steps to keep code compatible with both? The major differences between .NET Core and the .NET Framework: [...] APIs — .NET Core contains many of the same, but fewer, APIs as the .NET Framework, and with a different factoring (assembly names are different; type shape differs in key cases). These differences currently typically require changes to port source to .NET Core. While I understand the motivation, this at first sight looks like something that will be with us for a long time, and could make life more difficult especially for library authors, who need to potentially target both 'platforms'. [Disclaimer: haven't used .NET technologies for a very long time and might be horribly wrong here]

At my shop we have been using ASP Core since RC1 and have been quite happy with it. The tooling feels a lot like Node.js in a way, much different from any previous .NET development. It's awesome to have C# be deployable as docker containers on Linux hosts. My biggest gripe so far has been that Nuget doesn't have a way to search only for libraries that are Core compatible.

Microsoft is about 5 years too late with this. I'm sure their MVC stack is fine, but this isn't a problem needing a solution in 2016. There are dozens are frameworks in your favorite language that can deal with taking HTTP requests, grabbing data from a backend, and spitting it out as JSON. They all run fine on Linux servers, are easy to develop on Mac. C# is a nice language too, but I'd need a compelling reason to jump from Java / Scala over to .Net. And JetBrains puts out products just as good as Visual Studio for every major language. The one thing that might make me consider this would be MS implementing the actual valuable part of .Net to Linux, Mac, and others: the desktop GUI libs and Visual Studio GUI tools. Of course this will never happen since the MS dev tools team is beholden to the Office and OS departments. Instead, I imagine .Net core will not gain much traction.

Interesting name choice considering they have already had a .Net 1.0. I mean I get it, I understand why they chose to make this more of a 1.0 release but for those already in the .Net ecosystem it seems a little confusing to me.

malekpour 10y ago
It could have been more confusing by bumping versions. They first tried ASP.NET 5 and ASP.NET MVC 6 and EF 7 and there was no simple migration path from older version. Now they are all Core 1.0
recursive 10y ago
Excuse me if this was already obvious, but the word "core" designates a new product line, starting from 1.0. Obviously, it's informed heavily from the old .net framework, but it's not backwards compatible with it.
- BinaryIdiot 10y ago
  Sure it's obvious. Like I said I "get it" it's just core has always been a part of .Net just less directly referred to so my first thought was this was .Net 1.0's core until I started reading through the link. Overall I think it's a good move just a little confusing (unless I'm the only one) for those who have done .Net work before.
- lmickh 10y ago
  This is just a personal view, but my first instinct when I read about product "CoolApp" and "CoolApp Core" would be to assume core is a subset of the first. Not a new and re-engineered product line. I could see why others might see .Net Core as a parallel product as opposed to a new one.

Does this represent some kind of change for .NET? Why is it called 1.0?

Because it's the first version of the xplat .NET (the .NET Core) supported by Microsoft (mono already does an amazing works as xplat, and have done that for years). It's not confusing if you work in .NET, the .NET Framework 1.0 was released in 2000..

I was really hoping for ARM support at least as far as RasPi goes for 1.0. But still very good news I personally love .Net it's nice to be able to use it cross platform without having to work specifically around mono.

oblio 10y ago
From what I see Samsung has been contributing on that front. They said in the announcement that Samsung has joined the Dotnet Foundation.
- dogma1138 10y ago
  Yeah, the only problem with Samsung is that they most likely going to make builds for the Exynos based SOC which isn't that wide spread. The ARM ecosystem is quite fragmented and depending on how you build your software it's not as portable as one would assume. It's also not clear which instruction sets they are going to be aiming for Exynos started with ARMv7 + all the stuff that Samsung added to it, but the newer ships are ARMv8. The Raspberry Pi still uses ARMv6, 7 and 8 depending on the exact model with the newer RasPi compute, and Zero models still running the old BCM2835 ARMv6 CPU's. So I'm hoping for a more or less clean stock ARMv7 and ARMv8 builds for the .NET core coming out sooner rather than later, I also hope they'll release the X86 version to more platforms than Windows since running it on something like an Intel Edison which comes with a 32bit ATOM CPU will be quite cool. .NET is quite powerful and for my taste it's considerably better than Node.JS (I don't like Javascript, this isn't some technical observation just personal preference) but I do like C# and F# quite a bit and having the ability to run the same code across multiple platforms makes me excited for IOT/Embedded devices again especially considering that I don't have to work through some of the headaches that come with Mono (some pun indented).
  - oblio 10y ago
    Well, I imagine that if someone offers support for those platforms they won't say no. But they'd probably also need for stuff such as the CI chain.

      .NET Framework = the whole shebang, the full runtime including Windows-only bits. .NET Core = portable subset of .NET Framework. Therefore not entirely compatible with .NET Framework. ASP.NET Core = portable rewrite of ASP.NET. AFAIK not fully compatible with previous versions.

I was expecting they would fix the Uri class on Unix (https://github.com/dotnet/corefx/issues/1745 https://github.com/dotnet/corefx/issues/1745) before releasing 1.0 :( Now I fear their backwards compatibility policies will prevent to fix it later. So much for crossplatformness...

Way too many compatibility issues unaddressed by that PR to have a hope of getting anything changed there.

A couple months ago I installed .NET core on a Ubuntu virtual machine running on the Windows 10 hypervisor, and was able to get a MVC5 app running using Visual Studio Code. As someone who really loves Visual Studio (it made me expect a lot more from my tools) and C# (it made me expect a lot more from my languages), it was an exciting moment. I actually took a selfie with my monitor. It was still a little rough: the "getting started" instructions ONLY worked on Ubuntu 14.x and not Ubuntu 16.x, and my PR to the documentation pointing this out was nixed. (I notice they've since added a disclaimer: https://docs.asp.net/en/1.0.0-rc1/getting-started/installing-on-linux.html#installing-on-ubuntu-14-04 https://docs.asp.net/en/1.0.0-rc1/getting-started/installing...). I really hope to someday be able to build projects with React and a .NET core WebApi and be confident that my teammates will be able to get the project running on their macbooks without kms.

MVC 6 is the version that works best with Core, although they don't really refer to it directly much any more. Both MVC 6 and Web API 2 are now part of Core. They're just packages like everything else.

They link to some benchmarks in the article: https://github.com/aspnet/benchmarks https://github.com/aspnet/benchmarks (they're a little hard to read on mobile, but I think the tl;dr is "plenty fast" (or to quote the article: "Our lab runs show that ASP.NET Core is faster than some of our industry peers. We see throughput that is 8x better than Node.js and almost 3x better than Go, on the same hardware. We’re also not done! These improvements are from the changes that we were able to get into the 1.0 product.")

Scott Hunter of MS did an interview not so long ago re .NET, Kestrel (the new libuv HTTP server they build), and their march to build up as a top contender for Tech Empower. http://dotnetrocks.com/?show=1291 http://dotnetrocks.com/?show=1291 They have a team who does it all for fun and has an impressive testing environment build out. Fascinating to listen to given today's new. I listened a few weeks ago myself. I have friends at work who liked C# and moved on to frontend. The fact they are so less interested in .NET now is amazing to me as I finally want them to teach me to use ... on Linux!? I never thought I would say that. Haha.

I don't see mention of FreeBSD anywhere in the .NET Core 1.0 announcements -- has official support for FreeBSD dropped or been postponed?

Voloskaya 10y ago
* FreeBSD is listed on CoreCLR GitHub repo (https://github.com/dotnet/coreclr https://github.com/dotnet/coreclr). See current build status here: http://dotnet-ci.cloudapp.net/job/dotnet_coreclr/job/master/job/release_freebsd/ http://dotnet-ci.cloudapp.net/job/dotnet_coreclr/job/master/... * Also, see doc here (last updated in feb though): https://github.com/dotnet/coreclr/blob/master/Documentation/building/freebsd-instructions.md https://github.com/dotnet/coreclr/blob/master/Documentation/... * Laslty, FreeBSD arrived on azure last week, so it would be quite surprising if support was dropped.
- montyedwards 10y ago
  I understand, but none of those links are the .NET Core 1.0 release announcements. And the download page for .NET Core 1.0 doesn't mention FreeBSD at https://www.microsoft.com/net/download#core https://www.microsoft.com/net/download#core

Do we officially have better-than-Java on all platforms now?

interdrift 10y ago
Looks like it.
16bytes 10y ago
Language and tooling wise? Yes, or very close to it. There's a lot to be said about the huge amount of value in the main maven repository vs. what's in nuget. Java's decade long head start in that area doesn't seem so huge when you look at what the node.js community has put together in only a few years. If you were considering .net on a new project, however, I would probably recommend comparing something like Scala. Scala has the benefits of being a "modern" language like C# with the full support of all or nearly all of the existing JVM projects. That being said, there are a growing number of reasons to choose .net on non-windows platforms.
- oblio 10y ago
  I'd argue that it will be a while for Nuget to catch up. When I go on Maven Central I expect every library to be cross platform except for those marked as platform dependent. For Nuget... all bets are off for now. It's the exact opposite, I assume that things are not portable or at least have not been tested on say, Linux.
- rbanffy 10y ago
  > Java's decade long head start in that area doesn't seem so huge when you look at what the node.js community has put together in only a few years. It's easier to follow than to blaze a path. We have learned from Java and can, hopefully, avoid those pains.
PopsiclePete 10y ago
Yeah but so what. If the "best" language always won, why isn't the entire world running on Haskell and Rust or whatever? Java's eco-system is ginormous and it's deeply entrenched as the "corporate stack" in non-MS shops, with more than 15 years of history. I'm afraid this is just too late to make a big dent. C# is nicer than Java, but not that much nicer to warrant switching over or rewriting your stuff in a very immature eco-system. Maybe they're hoping to capture some of that elusive start-up market- and mind-share? That one is already pretty hostile towards MS... Either way, this is a good thing, I just wish they had done this in 2005 or so.

F# doesnt work ootb with sdk preview2. Work ok with preview1 of SDK (win/ubuntu/osx/docker), but preview2 has a bug, the fix is in progress ( ref https://github.com/dotnet/netcorecli-fsc/issues/12 https://github.com/dotnet/netcorecli-fsc/issues/12 ) and will be published a nuget package with fix soon.

- ubertaco 10y ago
  Seconded. I saw the announcement and immediately went to grab the docker image and give it a shot with F# via "dotnet new -l F#" and go. It restored and built, but didn't run. So v1.0 is broken, I guess?
  - Eyas 10y ago
    I don't think so. It means that the tooling is broken, which is not at 1.0 yet (still in `preview2` I believe).
    - enricosada 10y ago
      Exacly, the preview2 of the sdk, atm, is broken for f#. Not the .net core, that's ok. new console/lib templates are going to be published (with the fixed fsharp compiler/library package), that's all.
      - ubertaco 10y ago
        Still a little odd for a release announcement. It feels disingenuous to only afterwards make the fine-grained distinction that yes the libraries are technically v1, but the tooling is still in preview. Kinda like announcing your new line of cars is ready for purchase today! Except that down in the fine print you might find out that the engine is ready to go, but the steering wheel, headlights, dashboard, and pedals are all still in development and so it's justifiable that they're broken.

SoapSeller 10y ago

It's fascinating how Microsoft's marketing moved from ".Net - One platform with multiple languages" to "This is .Net - here some samples in C#"(without mentioning C# by name anywhere in the page). I think that .Net would be much better if they had this kind of focus in dev side from the start. *Hides from the f# mafia.

Even if this isn't the final release, I'm confused why they would include version numbers in the package name at all. One of the reasons of having a package manager in the first place is to avoid things like this.

FYI, from the announcement. Probably the most important part at the end, italicized by me. Also note (elsewhere) that licenses are MIT and Apache2: .NET Core Tools Telemetry The .NET Core tools include a telemetry feature so that we can collect usage information about the .NET Core Tools. It’s important that we understand how the tools are being used so that we can improve them. Part of the reason the tools are in Preview is that we don’t have enough information on the way that they will be used. The telemetry is only in the tools and does not affect your app. Behavior The telemetry feature is on by default. The data collected is anonymous in nature and will be published in an aggregated form for use by both Microsoft and community engineers under a Creative Commons license. You can opt-out of the telemetry feature by setting an environment variable DOTNET_CLI_TELEMETRY_OPTOUT (e.g. export on OS X/Linux, set on Windows) to true (e.g. “true”, 1). Doing this will stop the collection process from running. Data Points The feature collects the following pieces of data: The command being used (e.g. “build”, “restore”) The ExitCode of the command For test projects, the test runner being used The timestamp of invocation The framework used Whether runtime IDs are present in the “runtimes” node The CLI version being used The feature will not collect any personal data, such as usernames or emails. It will not scan your code and not extract any project-level data that can be considered sensitive, such as name, repo or author (if you set those in your project.json). We want to know how the tools are used, not what you are using the tools to build. If you find sensitive data being collected, that’s a bug. Please file an issue and it will be fixed.

Good news! Now time for all the library and framework authors to add support for .NET Core.

the asp.net core changed a lot between rc1 and rc2 (because moved to .net sdk instead of dnx). The normal libraries or console app not too much
- jsingleton 10y ago
  It depends on if you want to run ASP.NET Core on .NET Framework 4.6 or on .NET Core 1.0. It's not just the SDK that is new, Core console apps are pretty recent too, as previously it was mainly for web apps.

Does Microsoft have some diagram or something that shows how all the .NET things fit together (on Linux)? The C# development I've done was... fine, but that was seven years ago and it's like Java in the sense that it's an amazingly complex thing to grasp and keep up with. Understanding how everything is layered is pretty complicated at this point.

Does this still use mono's jit and GC on mac and linux? Last I checked mono's GC is conservative and the jit isn't as good as the .NET one.

mellinoe 10y ago
It does not; it uses the same JIT and GC as the Windows version of .NET Core, and the code is also shared with the (full) .NET Framework that ships inside Windows. Actually, this has always been the case for .NET Core, but you may be thinking of our older preview versions which gave you the option to run your app entirely on mono. (I work on .NET at Microsoft)

If I'm an experienced Python developer who develops a lot of websites and APIs using Django or Flask and SQLAlchemy, is there any reason to try this stuff? C# is a great language, but what about the libraries? What replaces Flask? What replaces SQLAlchemy? How do I deploy? Looking for some practical reasons to invest time on this if Windows development is not in my roadmap.

Flask - Nancy SqlAlchemy - EntityFramework, nHibernate Deployment - AppVeyor (cloud), TeamCity/OctopusDeploy (self-hosted) Having said that, there is probably very little reason unless you're just doing it out of pure interest.

No. If you really want a high performance Windows friendly server software, try Java. But honestly I would not use .net for anything past excel plugins.

Well, besides libraries, performance. .NET supports proper multithreading (no GIL) and it is also much faster than CPython. If IronPython gets ported to .NET Core (maybe it already has, I don't know), then you'd get those benefits for free.

I've mixed feelings about this release, because it seems a bit early to me. Some fundamentals will change soon (project.json replacement) and I am still not able to get debugging to work in VS Code on OSX. The whole situation in the .NET Core space was very confusing for the last months and this trend seems to continue. This is sad, because I'd love to code in C# on any platform and that things would just work as advertised on the website. Edit: Debugging works now for me, after the .NET Core Debugger was automatically installed in the background!

- mattmanser 10y ago
  I also think they've made a terrible decision, the first-class support for DI is a bad direction which has made many simple concepts like config settings into absolute farces that take 5 lines of code. It's code "purity" over usability. It's putting the core dev team's principles over their customers actual need, completely violating KISS, DRY and YAGNI. DI really is our generation's factories. I'm already seeing projects written by people who don't understand it making utter nightmare spagetti code, worse than any code I've ever seen. It's nasty scaffolding code which is a symptom of limitations of the language, definitely not code anyone should ever actually be wasting time writing. Instead of recognising it's a flash in the pan, the core team have embraced it and are trying to force it down everyone's necks, and a lot programmers simply don't get it and are making an utter mess instead.

I don't know of any green threads in .NET -- at least, not built in. However, .NET does have a built-in thread pooling / task execution service. You generally interface via `System.Threading.Tasks.Task`[0], which has static `Run` functions, or use the `Factory` property to get the underlying `TaskFactory` for more fun. Since the executors are pooled, the creation costs will be amortized over your program's lifetime. Then there's `async`/`await`[1], which is built on top of tasks.

  I remember that a long time ago, .NET threading was implemented in such a way that it should, in theory, support Win32 fibers. It's why all the low-level .NET APIs don't use the OS thread IDs, but instead have their own IDs, and require explicit mapping. I believe that it was abandoned as a supported scenario a while ago, though. But you can still see artifacts of that in the docs, e.g.: https://msdn.microsoft.com/en-us/library/system.threading.thread.managedthreadid(v=vs.110).aspx https://msdn.microsoft.com/en-us/library/system.threading.th... "The value of the ManagedThreadId property does not vary over time, even if unmanaged code that hosts the common language runtime implements the thread as a fiber."

hackaflocka 10y ago

Is there a primer somewhere that explains simply what the difference and dependence is between .NET (core, foundation), ASP.NET (core, foundation), Xamarin, Visual Studio (in all it's different flavors including VS.NET etc.) and Visual Studio Code? I tried Wikipedia, and Microsoft's own homepages for each, and am even more confused. I'm a hierarchical thinker, and a hierarchical tree explaining the above would be very very helpful. Disclaimer: I haven't downloaded any of these yet. I usually don't until I've understood something. Bonus question: If I want to develop websites and electron apps using: HTML, CSS, Javascript and PHP, what's the minimum set of technologies (or whatever it is that Microsoft is calling them these days) I will need?

oblio 10y ago
Dotnet Foundation = NGO that manages various legal and org things for .NET. Think FSF for GNU. .NET Core = cross platform software development platform. Includes a VM, compiler, tons of libraries. ASP.NET Core = HTTP server + server side .NET libraries. There is no ASP.NET Foundation, it's all part of the Dotnet Foundation. Xamarin = .NET libraries for mobile development. Wraps Android/iOS native libraries. Visual Studio = native Windows IDE for .NET and other languages. Visual Studio Code = portable, Electron/HTML 5 IDE for Javascript/Typescript and other languages. You probably want Visual Studio Code for HTML/PHP. But you should check out .NET Core, it can replace PHP. By the way, if it works, it works, but I find it better to research and do at the same time. Downloading only after you've understood the org chart seems a bit too radical for me :)
- hackaflocka 10y ago
  Thanks. Very helpful. Last 2 Qs: is Framework different from Core? And how does Windows Presentation Foundation fit in all this?
  - oblio 10y ago
    .NET Framework is the old .NET Framework. It's basically the entire shebang, tied to Windows: VM, class libraries, etc. .NET Core is as the name says, just the "core" of the .NET Framework, the part that's cross platform. However, I'm not sure that at this point the code's common, I believe at least a part of it has been reimplemented. I think that in the future .NET Framework will be based on .NET Core. Therefore .NET Framework will be .NET Core + Windows specific bits. WPF is the fancy name for a .NET UI toolkit for Windows, basically. Think of it as a Windows-only GTK.

eperfa 10y ago

I might be missing something here, but does this mean that .NET Framework and .NET Core have diverged, and you need to take extra steps to keep code compatible with both? The major differences between .NET Core and the .NET Framework: [...] APIs — .NET Core contains many of the same, but fewer, APIs as the .NET Framework, and with a different factoring (assembly names are different; type shape differs in key cases). These differences currently typically require changes to port source to .NET Core. While I understand the motivation, this at first sight looks like something that will be with us for a long time, and could make life more difficult especially for library authors, who need to potentially target both 'platforms'. [Disclaimer: haven't used .NET technologies for a very long time and might be horribly wrong here]

Microsoft is about 5 years too late with this. I'm sure their MVC stack is fine, but this isn't a problem needing a solution in 2016. There are dozens are frameworks in your favorite language that can deal with taking HTTP requests, grabbing data from a backend, and spitting it out as JSON. They all run fine on Linux servers, are easy to develop on Mac. C# is a nice language too, but I'd need a compelling reason to jump from Java / Scala over to .Net. And JetBrains puts out products just as good as Visual Studio for every major language. The one thing that might make me consider this would be MS implementing the actual valuable part of .Net to Linux, Mac, and others: the desktop GUI libs and Visual Studio GUI tools. Of course this will never happen since the MS dev tools team is beholden to the Office and OS departments. Instead, I imagine .Net core will not gain much traction.

I still don't understand what's a .NET project now, how to define one? what to checkin? is it still project.json? Or do we need another tool?

Any tutorial on how to build a .Net core web application specifically on Linux. There seems to be a lot to wade through docs wise with a lot of it still talking Windows.
