Hejlsberg seemed quite negative when it came to cross platform AOT compiled C# in several comments he's made, hinting at problems with both performance and maturity on certain platforms.
Sure, but this team's focus is on Typescript, not C# / cross-platform AOT; there's only so much time in a day. Others can pick it up I'm sure.
But I think it's also an indication that Typescript may be bigger and more important for Microsoft than C#/.NET is at this time. It's definitely much more used than C# is according to this non-representative survey of Stack Overflow (https://survey.stackoverflow.co/2024/technology).
Absolutely. Go is where it is because of the parent org's commitment to dogfooding it; strange that Microsoft is wasting this opportunity AND sending a negative message to .NET devs.
