Hi there! I'm a developer on the .Net team, and I heavily work on our IDE offerings. You can absolutely write a small program that is only a CLI, and our tooling is heavily tailored to make that a great experience. First off, you do

Hi there, C# Lang Designer here. :) We're always thinking about the bloat concern when it comes to language development. However, our philosophy on it is that bloat primarily comes when you add replacement systems that are expected to

Hi, I'm one of teh C# language designers, and I work on the compiler implementation as well. C# has never had a "simple tokenizer". Indeed, even the first language has complex lexical constructs that are part and parcel of t

Hi there! I'm the lang designer and i wrote up that spec. Could you clarify what you didn't understand about the indentation examples? I can work on clarifying them. Thanks!

Hi there, I'm the lang designer and implementor here. That would violate a core goal of the feature which is that the content itself doesn't need escaping. This sort of approach would require all users to have tooling that would

Hi, i'm the lang designer and implementor here. We absolutely do not normalize newlines as that would defeat the purpose of raw literals. The point here is that your content is not interpreted as that's the pain area that peopl

Hi. I'm the lang designer and feature implementor. To your question of "why?", we tried to cover the reasoning in teh proposal. But, the core reason is that today people do use strings a ton. And in many cases it's un

Hi, I'm the lang designer here. We looked into this. However, there didn't seem to be any benefit to this above just the N-quote version (which fits into how C# does strings everywhere else). In the above case, the `SQL(` and `)

Hi. I'm the designer of this feature. The reason for this is so that we can potentially have fenced string blocks in the future. for example: ```c# var s = """xml <Book><title/><&#x

Hi. I'm the designer of this lang feature. The specification covers this. However, to be clear, neither new line after the first `"""` is not part of the literal, nor is the newline before the last `"""

FYI, i work at MS (on a compiler team). The work-life balance is fantastic. I'm not sure where you got the idea that that isn't so. Thanks! :)

Hey DMarlow, could you clarify your question? A C# 7.0 program should run on pretty much any version of .Net after 2.0. Similar to C# 2.0-6.0. The only thing we ever really adopted in C# that needed a new runtime version was Generics.
