These days, you can run .NET entirely on Linux, without ever touching Windows or Visual Studio.
(Founder here) At Amezmo [0], we've supported .NET for sometime now, and recently added .NET 6 as an option for our managed app hosting platform.
Only the .NET Framework (for Windows) or Mono (for Mac and Linux) was required to run .NET apps. Since the early 2000s, development could be done with SharpDevelop (Windows) or its fork MonoDevelop (Mac/Linux) instead of Visual Studio as well.
csc.exe /out:HelloWorld.exe /target:exe Program.csHasn't Mono existed since 2004? Any Unity game has been running C# on many platforms by using Mono.
I'd recommend it to a Windows dev who wants to go crossplatform, but never to a crossplatform dev.
It's confusing if you have to deal with legacy applications running old versions of the frame I concur, but if you're on a greenfield project working with dotnet 5+ the experience is pretty good.
I work with vscode on nixos which is probably one of the most challenging Linux environments, and have experienced no blocks. I have had to install mono manually to work around some bugs and write a couple of patches as vscode can't write things where it wants to the read-only nature of nixos, but this is just part of the usual nixos experience.
TLDR: For me, if you're using linux and you wanna give dotnet a go, try it, you might also be pleasantly surprised.
