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 did all the things listed here and still nothing (VS2013 Update 3). I tried /setup, /resetsettings, deleting the stuff in AppData, deleting the registry keys. Still, User Types wouldn't be highlighted even in the default color scheme.
What helped in the end was opening the Fonts and Colors dialog, selecting Identifier, and making it Bold. Then removing the Bold. Instant fixage!
