Found a correlation:

When NuGet auto-pull is enabled, I run into this issue on VS 11 after about ~15 builds. Deleting the Packages folder and forcing a re-pull of dependencies on build corrects.

I also noticed that if I manually purge the obj/bin folders in the solution root, the solution is corrected.

Hope this helps.
