Also seeing as how I can't do the database diagrams and I have to use your .edmx file and database diagrams in order to complete the assignments, I get the following compile warnings using your version of the code:

Warning 1 Unable to update auto-refresh reference 'entityframework.dll'. Cannot find assembly 'C:\Users\Imar\Documents\Visual Studio 2012\Projects\Site\packages\EntityFramework.5.0.0\ lib\net45\EntityFramework.dll'. C:\BegASPNET\Chapter 14\Bin\entityframework.dll.refresh C:\BegASPNET\Chapter 14\

I don't get that. Why can't you create diagrams in SQL Server and build your own EDMX file? Just use SSMS.

That said, it sounds like your site doesn't have the EntityFramework packge installed. Hard to tell though with the limited information you're providing.

I am pretty sure that I installed the entity framework through Nuget. I will try to install it again and see if that is the cause of the problem.
Yes I went to Nuget Package manager and tried to download the latest version of Entity Framework and the package manager told me that Entity Framework already exists for the project. So that is not the problem or the cause of that error message when I try to compile the application.
