IgnoreInheritance does not work for reference types

[HerrLoesch]

I have following classes:

public class A 
{
    public  string Test { get; set; }
}

public class B
{
    public A MyA {get; set; }
}

public class C : B
{
    public string AnotherProperty {get;set;}
}

I have configured the filler as followed:

var filler = new Filler<C>();
filler.Setup().IgnoreInheritance();
var c = filler.Create();

I woul expect that Cs property "MyA" is null but its actually an empty A.
