It runs perfectly fine on Linux since .NET Core. There is only one relevant web framework: ASP.NET Core. Microsoft is as bad at naming things as it has always been, so that hasn't changed. They're pretty good about not deprecating too much in the web area now, the big disruptive change was from .NET Framework to .NET Core. The Windows UI stuff seems to be a bit of a shitshow in terms of deprecations, but I've no direct experience with it.
