I have a Debian system on my laptop for school, but I would like to program on this using C #, is there something similar to Visual Studio (not visual studio code) that I can use to do this without the help of Wine etc?
Well, Visual Studio is the central environment for this…
Maybe these links will help you further:
https://stackoverflow.com/...tudio-code
https://docs.microsoft.com/...tudio-code
https://code.visualstudio.com/Docs/languages/csharp
https://docs.microsoft.com/...arp-module
Otherwise I wouldn't know of any other way straight away.
I would very much like to do without microsoft there, even if the language is more or less of those, which often leads to errors and other unpleasantness, but thanks anyway
Well, if you just want to write code, very puristically without the .Net Core Framework: https://www.monodevelop.com/download/#fndtn-download-lin
To do this, you first need mono: https://www.mono-project.com/download/stable/#download-lin
even if the language is more or less of them
Therefore it is very limited even without their SDK.
which often leads to mistakes and other unsightly things
In what way?
