I am not sure but possibly you do this in one project (project A) and in another project (project B), you only add a reference for that project (project A). (this was assumption part)
If you add the EF 6.1 reference (NuGet) in project B, you will see the error cleared. I hope :)

Had same problem. Finally got to know the reason that EntityFramework assembly reference in 2 projects were different. Made them same (6.0) and it worked.

Solution 3

This can happen if your project name conflicts with a nuget package you referenced. I wasted about 3 hrs before I realized what is going on

Please focus on current issues. This one is more than five years old.

If you called your project "EntityFramework", you did something that would be very rare to occur.
