Somehow part of my syntax highlighting for C# code has disappeared in the VS 2012 IDE. Uninstalling, rebooting, and reinstalling does nothing, nor does resetting the colors
If you still have this issue try ResetSettings (worked for me)
NOTE: this will reset the Visual Studio 2012 settings :)
1) close vs.
2)open cmd (as administrator).
3) go to devnev.exe folder (something like "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE" ).
4) type "devnev.exe /ResetSettings"
5) open vs and look at the beautiful colors
