How to implement inheritance Table-Per-Type in Entity Framework 4.3 via Code First approach?

Question

I have this class hierarchy in code:

[Table(\"A\")]
public class A : IIdentification
{
    public int id { get; set; }
}

[Table(\"B\")]
public class B : A
{

In mapped inheritance you don't have accessible navigation property to parent entity unless you want to model another relation. Inheritance is "is a" relation so B is A while FK is "has a" relation.

Here you have a great walkthrough for TPT inheritance.
