I was run a downloaded application from the internet. If I used migration in PM console, I got this error.
I spent a lot of time searching for a solution.
I found Microsoft's reference of common errors.
ERROR: Type is not resolved for member 'System.Data.Entity.Migrations.Design.ToolingFacade+UpdateRunner,EntityFramework, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
NOTICE: This error can be caused by specifying an incorrect startup directory. This must be the location of migrate.exe
solution: check your application (directory) path if not contains &, because it is reserved and throw this error.
I copied my application to another path and its working fine.
This post probably can help and save time to someone, who has same problem.
