Still same exception after uninstall of EF and reinstall...
Thank in advance.
Did you deploy the solution?
I mean it's telling you what is wrong. It the program's manifest wants the EF DLL for EF6, version such and such with the public key-token, which is what you picked up in development of the program. Either the DLL is not in the Bin folder, the wrong version
of the DLL is there in the Bin folder or a dependency DLL the main DLL needs is not there in the Bin folder.
If you find the post has answered your issue, then please mark post as 'answered'.

uninstall the EF nuget
re-install the EG nuget
Also, do you have just the MVC project in the solution or you have MVC and another project that references EF?

I figured out the issue. Big bang migration. Started over with smaller migrations with not a problem...
Thank you for your help.
