I also have two collegues using Apple silicon, also no problems there.
The official aspnet core web framework is (in my opinion) good enough that you don't need anything 3rd party.
The GUI story is not a good one though, and if I were to write a GUI program I'd reach for Avalonia (3rd party, free).
I use Rider as IDE, but there are multiple other options.
With the recent performance improvements (Span, Memory, Intrinsics, etc) it's possible to write quite performant C# these days, and with low GC pressure.
