C# has value types, stackalloc, simpler FFI and a rich SIMD API, offering far better control for low-level code than Java. I don't feel green threads is a system level concern, and while Java's ecosystem is huge, it's also very enterprisey. Also, I'd disagree with more open, C# is under a more permissive license and Oracle has actually been litigious over Java.

While I also favour C# over Java, the languages, the runtimes it is a bit different, given the wide spectrum of JVM implementations in the wild. Lets not forget that C# only exists because Sun won the lawsuit over J++, where several C# features were born (J/Direct => P/Invoke, events, JFC => Windows Forms, COM support), and Ext-VOS (the COM next generation runtime) paper refers to J++, before COOL became C#, and J# was introduced as migration path from J++. Ironically, after all these years, as means to keep Azure relevant for the Java community, Microsoft has become a OpenJDK contributor by acquiring jClarity, including ARM support on Windows, better escape analysis, and has their own distribution. And VSCode plugins for Java, developed in collaboration with Red-Hat, are much better than C# Dev Kit, without requiring a Microsoft account.

  The only features DevKit offers are Visual Studio style solution and test explorers. You don't need either DevKit or a Microsoft account to use base C# extension. The description is confusing though. I suppose they did the whole "rebrand" thing because for years everyone thought poorly of experience of writing C# in VSC while it has always been semi-decent (depending on your skills) and got better recently, especially after moving to Roslyn-based LSP from Omnisharp.
