Entity Framework complex relationship

I have class A which inherits from class B, at the same time class A has many instances of B. Class B contains class A property as a reference.

I'm looking for the best way to map this relationship using EF Codefirst.

Solution

  • A is NOT inherited from B. They have a few common properties like this:

    class ABCommon
{
    //common properties here
}

class B : ABCommon
{
    public virtual A A { get; set; }
    //this property makes everything crazy if A inherits from B
}

public A : ABCommon
{
    public virtual ICollection<B> Bs { get; set; }
}

    It's just a simple 1-to-many relationship between A and B.
