Some people say to reinstall entity framework with the following command:
Install-Package EntityFramework -IncludePrerelease
But it didn't work for me since I have it installed, so I find a way to force reinstall the package which works! The command as follow:
Update-Package -reinstall EntityFramework -IncludePrerelease
