I'm brand new to the Entity Framework and trying to learn all it can offer. I'm currently working my way through the MVC Music Store tutorial which includes the following code:

public ActionResult Browse(string genre)
 {
    // Retrieve Genre and its Associated Albums from database
    var genreModel = storeDB.Genres.Include("Albums")
        .Single(g => g.Name == genre);

    return View(genreModel);
 }

as I'm working in VB I converted it like so:

Function Browse(ByVal genre As String) As ActionResult

            'Retrieve Genre and its Associated Albums from database
            Dim genreModel = storeDB.Genres.Include("Albums"). _
                    Single(Function(g) g.Name = genre)

            Return(View(genreModel))
        End Function

The problem is I'm getting the following exception:

Invalid column name 'GenreGenreId'.

Which I know is true, but I can't for the life of my work out where it's getting 'GenreGenreId' from. Probably a basic question but I'll appreciate any help in the right direction.


As per requested here is the source for my classes:
