                        TypeBuilder tb = module.DefineType("ConcreteFoo",
TypeAttributes.Public, typeof(BaseType));

                        Type t = tb.CreateType();
                        Console.WriteLine(typeof(IFoo).IsAssignableFrom(t));
                }
        }
}

It prints False while it should print True.
