Happy New Year! As you settle back into your work environments, please remember to see if you are running any pre-release versions of Visual Studio 2012 or Team Foundation Server 2012. This software will stop working on January 15, 2013 and cannot be extended.
You can check your Visual Studio 2012 development environment by clicking on Help –> About and inspecting the version. If you see Beta or Release Candidate (RC) you’ll need to upgrade to RTM (or Update 1, which is the newest post-RTM release).
For Team Foundation Server, launch the Team Foundation Server Administration Console.
