I have developed .NET solutions on Linux over 8 years now (and about 10 years on Windows before) and would say the quality of development in Linux is even better than in Windows today. Sure you can't use Visual Studio in Linux, but you can use VS Code or Rider, which I would prefere anyway.
If you aren't it doing GUIs, which means you need to go into FOSS ecosystem with Avalonia or Uno, and if you aren't doing anything with profiling or debugging visualization of threaded code and a few other goodies that VS has for .NET and they will never make available into VSCode extension.
Also the VSCode extension for .NET has the same license as VS.
