Thanks for the PR. Aside from the wrong positioning of the Changelog entry, I tested the changes on both Windows and Linux (WSL).Here are my findings:
The first three commands (ide uninstall dotnet, ide install dotnet, and ide env) work as expected on both operating systems.
However, running ide dotnet --info still throws an error on Linux (WSL). Since this ticket is specifically about making dotnet fully functional on Linux, we should look into this.
I have attached the log files for both Windows and Linux to this comment. Tip: You can use lnav or fzf to navigate through them easily. It might be an edge case with my specific WSL configuration, though I suspect it could be a general Linux issue.

My Suggestions, Could you please double-check the command on Linux? If this requires specific local setup, it would be great to update the PR description with the necessary prerequisites for testing.

However, running ide dotnet --info still throws an error on Linux (WSL).

I think we need to give this an extra look. I'm testing on Arch, could it be something to do with WSL? Regardless, I'll give it a proper look tomorrow morning

Afer a call with Majeste we confirmed that his issue was because of a missing library on his setup, moving this to Review
