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.

Answer 2

I just used this command:

Update-Package EntityFramework -Reinstall

Answer 3

In my case, helped installing EntityFramework package first:

Install-Package EntityFramework

and then installing EntityFramework.Migrations again:

Install-Package EntityFramework.Migrations

Answer 4

Not the best solution but to get it to work again I had to re-install the EntityFramework.Migrations package. After it had reapplied the Init.ps1 it remembered all the commands.

Answer 5

After trying everything else, the only way I could get my EntityFramework Migrations commands back was to run the following from the "Package Manager Console":

Import-Module \*PathToSolution*\packages\EntityFramework.5.0.0-beta2\tools\EntityFramework.psd1

After running the above, Add-Migration, Update-Database, etc. was available again.

Answer 6

Restarting Visual Studio solved the problem for me...

Answer 7

For me the problem was the Nuget version.

1. uninstall Nuget Package Manager.
2. restart Visual Studio.
3. installed new version of Nuget Package Manager.
4. then re-start Visual Studio again
