To be fair C# is vastly different in terms of semantics compared to C++. There's a lot of areas where it's not viable to use C#, and IMHO it also has its own share of legacy and bad decisions from its "Java clone" days that make it impossible to prefer it to C++ sometimes.

Btw Microsoft is definitely interested into adopting new languages, just look all the effort they've been pouring into Rust lately.

Rust is now the official system programming language for Azure infrastructure, alongside managed languages, and it appears there is a soft spot to use Go instead of C#, when looking at what Azure opens up.

WinDev, Office and XBox is another matter, they are deep into C++ and COM culture.
