The development experience with Rider is also great on Linux. I think you need to be more specific with the complaints because I have many beefs with Microsoft's approach to many things, but I could not pick up on what you meant.
GUI stuff from Windows depends deeply on Win32 and how Windows's core APIs work. So expecting Microsoft to port stuff like .Net Windows Forms is meaningless. They are open source though. Maybe with some completion effort Wine can run them.
