Answer 1

Occurs with EF5 RTM, VS2012 RTM.

I experienced this problem today. I executed "Update-Package EntityFramework" in the PM Console. No changes were reported by NuGet and the problem persisted. I then restarted VS2012 and re-attempted Update-Database and it worked as expected. It's not clear what caused this problem, it's also not clear whether the Update-Package contributed to correcting it or not.

First try restarting Visual Studio, then try Update-Package EntityFramework followed by a restart.

I just used this command:

Update-Package EntityFramework -Reinstall
