Entity Framework error initialization

.net entity-framework

Question

I have a MVC .Net 4.5 project and i have installed Entity Framework.

The version installed was the 6.0.1. But when i run the application, it returns an error:

Could not load file or assembly 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of it's dependencies. The located assembly's manifest definition does not match the assembly reference. (Excepción de HRESULT: 0x80131040)

So, after i've seen that, i've uninstalled EF, and installed it again, but the 6.0.0 version. However, the error persist!

Do you know what's the problem?

Thanks people

Accepted Answer

Check your app.config or web.config. Maybe here wrong version number. Also check EF library number in references.
