C#, eh... I'm not sure what to think of that. Fortunately that means that we Linux folk don't need to use Wine to run it. Unfortunately we do need to use Mono. It's not as bad as needing Wine, but not as good as having the app run natively...
Jut for reference, on openSUSE to install mono and run the program:
sudo zypper install mono-core mono-winforms
Its appearance is as if someone had enabled the Motif theme, but it runs. I haven't tried to do actual editing with it yet, though. Maybe some more packages are needed for it to do its job.
Also argh, CRLF is mandatory? Git will not like that one bit... Or, well, it wouldn't if it wasn't as scalable as it is right now. Just have to remember to add a .gitattributes file to the repository, like this:
*.xml text eol=crlf
