I have a solution with lots of class library projects and a MVC 4 website using them. I tried to upgrade .NET Framework from 4 to 4.5 and upgrade those class library projects, that each are using EF 4.4 models, to EF 5. But I'm getting "Multiple versions were encountered".

Here's what I done so far:

  1. Changed target framework to 4.5 on all projects in solution
  2. Updated reference to EF 5 on all projects using Nuget package manager
  3. Changed my Web.Config in MVC project "section name="entityFramework... 5.0.0.0.."
  4. Checked if multiple .edmx files were generated, but there wasnt.
  5. "Cleaned build" + Restart didnt help
  6. Searched whole solution for 4.4.0.0 but all were 5.0.0.0
  7. ProviderManifestToken="2008" on all, same as before I started

What might be wrong here? I'm running out of ideas.

  • You can try a search for some wrong key inside the .proj files of the libraries. Hope that helps – Daniele Aug 08 '13 at 09:42

In WebConfig doesn't work in EF5
