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
I already had VS 2012 Pro installed on my machine. I then installed VS 2013 Pro and started facing this color issue. I then deleted the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\FontAndColors key and opened VS 2013. This approach solved my issue and the colors were back.
