its not just an apple thing. never been able to program c# for the same reason. any time there's some sort of account signup or license needed to code something, i refuse to participate.
python, golang, rust, etc. don't have any stupid hurdles to overcome so those are technologies i use.
The .NET SDK is readily available as a standalone download for almost all platforms now [1] which you can use to just compile on the command line and use any editor you like.
JetBrains Rider EAP is free to use I believe if you want a full IDE without needing to login (edit: it seems the EAP program is opened and closed at specific times [3])
I can’t remember if Visual Studio Community edition requires a login or not, but frankly even as a full time .NET developer I barely go near Visual Studio these days.
Overall the ecosystem is a little more open and dare I say “friendly” than Apple’s!

Install Vs Code and the C# plugin and you're in the game.
Never got around to making it though so there might be some pitfalls.
