Entity Framework Versions Issue

Have a class library and a WPF application and am trying to contain all the Entity Framework items within the class library and use an interface to get the info out. Everything is setup but I get this message each time I try it out:

Message "The type initializer for 'System.Data.Entity.Internal.AppConfig' threw an exception."

When I looked at the Inner Exceptions it appeared it couldn't find version 5.0.0.0 of EntityFramework and when I checked the Reference for it, it was 4.4.0.0. Tried uninstalling and reinstalling EntityFramework via NuGet but having no luck. Any ideas on what to try next?

App Config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>

  <entityFramework>
