How can I get user type C# syntax highlighting working again in VS 2012 RC?

Question

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

Answer 1

My problem was limited to having the "DateTime" type not showing up in light blue like other class names. I fixed it by simply switching back-and-forth between VS Themes. Discovered by accident. Much quicker than reset settings or repair install...

VS menu Tools -> Change Color Theme
