How can I manage EF 6 migrations in visual studio 2015?

Question

I started a new MVC project with EntityFramework -Version 6.1.2 using Visual Studio 2013 latest update. I made a couple of migrations and updated the database.

Answer 1

I did all combinations of reinstall or uninstall and install EntityFramework plus closing and reopening VS. The only thing that worked was deleting the folder packages in my solution folder and rebuild the solution to force all packages to download.
