Hm, I didn't realize .NET Core had been changed to an MIT license. That wasn't the case when I was working in C# on a regular basis.

My guess is that MS proprietary tooling still sucks out the air from FOSS tools, but I can't speak from experience there so I'll just admit I don't know how the ecosystem has changed since I worked in it.

Visual Studio is definitely still the ideal environment for writing C#, but JetBrains Rider is a solid alternative, and VS Code with the right set of extensions is probably "good enough" for most things.
