Using the Package Manager, re-install Entity Framework:

Uninstall-Package EntityFramework -Force

Then install it for each project:

Install-Package EntityFramework

Restart Visual Studio.

You can try:

  • Run VS as Administrator
  • Clean & Rebuild
  • Remove the obj folder

In some case you can use Update-Package -Reinstall to complete reinstall all package
