Nhibernate mapping Lazy load no-Proxy

Question

Hi a have following inheritance :

class A {

 } class B : A {

 } 
class C { 
    public A Product{get;set} 
}

and fluent mapping where i map C like :

References(x => x.Product).Cascade.SaveUpdate();

when i try to convert Product to B a get cast exception because nhibernate return a proxy of type A , i tried to set up lazy load no proxy for that property but it didn't work : References(x => x.Product).LazyLoad(Laziness.NoProxy).Cascade.SaveUpdate(); how can i fix it ? Thanks in advance

3 Options:

1) disable LazyLoading for this reference

2) ReferenceAny: stores the type of A in Table of C

3) Use Polymorphism instead of casting
