What would you like to do?
Stick this in an Editor folder in your project. Every time the solution file is recreated by Unity it will remove all the cruft that Unity injects into the file. Hopefully, one day, Unity will actually fix this on their end.
/*
v2: Matt Rix pointed out there's an undocumented ONGeneratedCSProjectFiles() callback
https://gist.github.com/MattRix/0bf8de88e16e8b494dbb
v1: Still available in the gist history if you want a FileSystemWatcher solution!
THE PROBLEM:
- Unity constantly rewrites its .sln files whenever you rename/add/remove scripts
- Their solution files includes a bunch of formatting/tab/etc settings
- Unfortunately, MonoDevelop / Xamarin Studio give these settings priority over your other defaults
(At least sometimes--over here I only get issues maybe once or twice a day)
THE SOLUTION:
- Strip out this entire block of settings whenever any .sln file changes
TO USE:
- Toss this script anywhere in an Editor/ folder
- Enjoy your tabs not getting constantly mangled!
Enjoy,
Matthew / Team Colorblind

With the new "MonoDevelop Solution Properties" option added in patch 5.1.0P1, is this still required?
