I developed an MVC 4 app targeting the .net framework 4.5, but my server only supports 4.0, so I did the downgrade to .net framework 4.0 and reinstalled my nugget packages. I downgraded EF from 6 to 5 too and it is working fine in my machine, accessing the database, etc. But when I run on the server, I get this error:
