Question

I’m trying to generate a Generic Repository. So far, so good.
But I get the same error as somebody else posted before:
Mapping to a nested class

The problem is that I am apparently trying to map a nested class. How can I fix this, so I do not map a nested class anymore?

EDIT:
That should not be the problem.

namespace MvcApplication1.Models
{
    public class MyContext :DbContext
    {

        public DbSet<ALBUM> Albums { get; set; }
        ...
}
}

where for example ALBUM:

[EdmEntityTypeAttribute(NamespaceName="MyDbModel", Name="ALBUM")]
    [Serializable()]
    [DataContractAttribute(IsReference=true)]
    public partial class ALBUM : EntityObject

Why is the class ALBUM not allowed to map?

Answer 1

This is the error message you’re getting.

System.InvalidOperationException: The type ‘ContactModels+Contact’ was not mapped. Check that the type has not been explicitly excluded by using the Ignore method or NotMappedAttribute data annotation. Verify that the type was defined as a class, is not primitive, nested or generic, and does not inherit from EntityObject.

AND THIS is the class you’re trying to map:

[EdmEntityTypeAttribute(NamespaceName="MyDbModel", Name="ALBUM")]
    [Serializable()]
    [DataContractAttribute(IsReference=true)]
    public partial class ALBUM : EntityObject

You’re inherting from EntityObject. It says right there. You can’t map it.
