It sounds like the code is still using some values that are cached on the client after the upgrade. How long ago was it that you upgraded the server?
To test whether that is it, rename your cache folder (with VS 2012 closed) and launch VS 2012 again so it recreates the cache from scratch.
C:\Users\\AppData\Local\Microsoft\Team Foundation\4.0
We resolved our issue with this by running VS 2012 with our domain credentials. We use VMs for development, so we do not directly login into the domain. To run VS, we use the following (as a batch file):
runas /netonly /user: username "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe"
where username is your domain credential.
