title: The workspace version table contains an unknown schema version
body: <p>Just started up Visual Studio 2012 and opened my solution which is in source control with Team Foundation Server 2012 Express and encountered this, any ideas? Can't get latest, can't check in, everything appears checked out :( Basically my workspace is unusable right now.</p>
