Hello,

I am new to NHibernate. I spent few days by reading documentation of NHibernate and Hibernate, but I did not find the example of how to map some class which implements two interfaces - I want to use both interfaces for polymorphic queries.

- I have interfaces "IFirstInterface" and "ISecondInterface".
- My abstract class "SomeAbstractClass" implements both interfaces.
- I have interface "IThirdInterface".
- My concrete class "SomeConcreteClass" is inherited from "SomeAbstractClass" and is implementing "IThirdInterface".

Please can someone show me how to do it?

Many thanks
David S.

You don't have to map interfaces in any way in the mapping files. If you use an interface in a query, NHibernate will look through all the classes it knows about and select those that implement the interface.
