Not sure why the downvotes. The good news is that we should be very close to the end of that with GIMP 3 out very soon.
Earlier in the year they announced that it was expected in July or so. I hold out hope that they at least get it out this year. Once it is out, all will be forgieven. Let’s hope that we do not see as long of a delay next time.
Most .NET development is arguably superior on Linux than on Windows. I would certainly say this for console, web or cloud, especially if you are using containers. Mobile dev is a bit more of a mixed bag. Obviously if you are building desktop Windows apps explicitly then that is better on Windows. However, if you are building cross-platform .NET apps ( eg. Avalonia or Uno ), you are back to Linux being better.
If you like a full IDE like Visual Studio then you want Rider on Linux ( which is better than VS even on Windows IMHO ). If you are a Visual Studio Code person, you can use that on Linux natively. Of course, if you are a neovim or Emacs user, we are back to Linux being better.
Many distros ship .NET in their repos these days. One issue with that is that you may want to update .NET more often than your distro does. While you can do that, I think it is best not to do that. For this reason, I think choosing a distro that stays up-to-date is best for .NET dev. My recommendation would be an Arch derivative like EndeavourOS. EOS includes .NET in the repos and provides very timely updates.
