Perhaps wasn't available at the time? It has remained relatively little known to teams that lived comfortably within WPF for years, luckily it's changing. .NET's GUI situation is a mess but Avalonia and Uno make it quite sane

Avalonia would have been a far, far better option.

FWIW Tiered Compilation has been enabled on by default since .NET Core 3.1. If the code tries to use refection to mutate static readonly fields and fails, it's the fault of that code.

No, slices in Go are more akin to ArraySegment but with resizing/copy-on-append. It does not have the same `byref` mechanism .NET supports, which can reference arbitrary memory (GC-owned or otherwise) in a unified way as a single (spec

In C# nothing stops you from doing `var t = Task.Run(() => ExpensiveButSynchronous());` and then `await`ing it later. Not that uncommon for firing off known long operations to have some other threadpool thread deal with it. Unless you li

using var stream = GetStream(); does not introduce new (lexical) scope, avoiding use means that the type system either has to understand move semantics (in case the stream is returned or move elsewhere, but then, what about sharing?) or hav

Wait, what? The => operator is just for lambdas, short-form returns and switch expression arms, which is as common as it gets! Have you never worked with any other language which lets you do these? var say = (string s) => Consol

Same here. And I’m not aware of quality issues with GxHash either. For large(r) inputs I’d expect it to be easily competitive. And it’s better than XXH3 on my M4.

If whatever you are doing is heavy on hashmap lookups (and you are ok with not rewriting into something more bespoke+complicated) - the faster hash function and the cheaper baseline cost of calling it - the better (i.e. XXH3 can have disadv

Quite a few languages "loved" by "Linux communities" tend to have rather rudimentary integration with Linux kernel's facilities or worse packaging story. For example, Go does not understand cgroups limits and needs

Most of the features that require Apache or community packages in Java ship out of box in .NET (or via extension packages). They also tend to be of higher quality and provide better performance.

IIRC all previous conversations about checked exceptions here ended up with the swift conclusion that they are heavily discouraged throughout Java code.

I suppose the difference of opinion comes down to whether you consider hiding side effects a good or a bad thing. And whether you want to have easy composition and cancellation (Go struggles with passing context around a lot, in .NET it&#x2

Usually dual APIs are offered when they do distinctly different things. Async calls on Socket go through epoll/kqueue via SocketAsyncEngine, which has observably different behavior to regular sockets. There is no such duality in high-l

In the end, .NET is going hybrid route. Circa .NET 10/11 Roslyn will stop emitting state machines and something state-machine-like will be produced by the compiler itself iff the asynchronous execution suspends, and will be otherwise p

The unit of comparison with BEAM processes are .NET tasks. The results are much less favorable to Erlang or Elixir in that case https://gist.github.com/neon-sunset/8fcc31d6853ebcde3b45dc7a...

To me a claim "how many things the Java ecosystem gets right that .NET gets wrong" borders on insanity if we consider having to interact with Maven or even Gradle on a daily basis after .NET's CLI and NuGet, or having to deal

Hmm, it should not be taking this much time unless you're running into an edge case - we have a fairly complex application that needs to pre-load a lot of data from persistence (no EFC though, it's an embedded DB) and over the wir

To be fair, old Entity Framework was on the heavier side. Still much faster than e.g. ActiveRecord but enough for Dapper to be made back then. The gap between them is mostly gone nowadays plus .NET itself has become massively faster and a

You are confusing platform-specific(!) GUI frameworks with the languages themselves, which have been long "divorced" from the platform they initially targeted.
