Entity Framework code first migrations throwing error

Question

Here is what I did before I got this error:

1. Installed EF (the pre release version, 6 maybe, I dunno)
2. decided I did not want, so uninstalled that and reins

Answer 1

I also faced this problem while using using code first migration. just update the entity framework version to Entity Framework Version 6.1.3 to resolve this. using command on Package manager console "Install-Package Entity Framework -version 6.1.3"
