Is it possible to develop mods on Linux?

[Densevoid]

Several years ago I did it. I used this tutorial:
https://blog.rubenwardy.com/2016/07/20/rimworld-install-monodevelop-with-dot-net-3.5/

But now it doesn't work with my linux mint 20. I almost lost hope of success. But maybe someone solved this problem?

This one is developped on debian stable https://github.com/b606/RimWorld-LanguageWorker_French, and mono/monodevelop are still working well. Basically I followed the instruction here without any special trick :
https://www.monodevelop.com/download/#fndtn-download-lin-debian

My only concern is that monodevelop is a cpu hog and I never managed to set RIMWORLD_MOD_DEBUG=??? correctly in order to use the monodevelop built-in soft-debugger.

Did you leave ".NET standart 2.0" in the "target framework" field?

I myself have not even checked whether it works or not. Trust the guide with their requirement downgrade mono to 3.12

And I'm already thinking of installing Windows for these purposes.

I have <TargetFrameworkVersion>v4.0</TargetFrameworkVersion>. you might try to copy my project setting.
Which version of Linux do you have ? If it is LMDE, we should be on the same version.
