How to implement table-per-concrete-type strategy using entity framework

Question

I'm mapping a set of tables that share a common set of fields:

So as you can see I'm using a table-per-concrete-type strategy to map the inheritance.

But...

I have not could to relate them to an abstract type containing these common properties.

It's possible to do it using EF?

Finally I created an interface 'Iggy' that contained the accessors to the common properties:

public Interface Iggy
{
  string modifiedBy { get; set; }
  DateTime modifiedDate { get; set; }
}

and used partial classes to implement it in the domain classes

public partial class Al:Iggy{}
public partial class Ben:Iggy{}
public partial class Carl:Iggy{}

C# is really very handy, and although I would liked to do it using a entity-framework feature, partials work like a charm : )
