Visual Studio: references in code not recognized?

Solution
I would suggest that you clear your Visual Studio temp files - it can often get confused about project structures and require a fresh start.
First, quit out of VS completely and restart it. If the problem is still there, find your VS cache folder and delete it, and then do a rebuild.

Problem
I have a solution in VS2008 (C#) that contains multiple projects. I just retooled some of the .csproj files for our build process, and suddenly while coding Project B won't recognize references from Project A in the class code...think the red squiggly lines under a variable type I've created. However, building the solution generates no errors. Why's it behaving like this?
