Reading this thread is the first I'm learning of this. Even with the enthusiasm expressed here, I'm still suspicious that there will be incompatibilities. Microsoft has a history of doing things a certain way.
That's your bias and not the language fault, everything works pretty much the same across every OS, I haven't developed non-UI C# apps on Windows since 2018 (because of course you need Windows to build WinUI and WPF apps, but you have options on macOS and Linux too)
GUI libraries might have some potential for improvement but I would reach for C# for any task that didnt strictly require a different language.
