Revisions to Entity Framework code first migrations throwing error

I figured out the problem. EntityFramework.dll needed to be in the GAC for Visual Studio to use it from the package manager.

Start Visual Studio Command Prompt (ensure you started Visual Studio as Administrator)
Go to your packages directory and find the EntityFramework package directory.
Go to lib\net45 (if targeting 4.5)
type: gacutil /i EntityFramework.dll

Note: It may be wise to restart the computer entirely at this point.

I'm not sure why Visual Studio stopped seeing the DLL, but this got me past this problem.
