Am I using IRepository correctly?

问题 I'm looking to use the IRepository pattern (backed by NHibernate, if it matters) in a small project. The domain is a simple one, intentionally so to allow me to focus on understanding the IRepository pattern. The lone domain class is Movie , with properties for Year , Genre , and Title . My intent would be to "get" movies whose properties match criteria of the aforementioned types. Convention seems to be to have a generic IRepository interface, similar to the following: public interface

问题 Let me start with my current setup, and then explain what I am trying to achieve. We are using NHibernate and trying to implement the IRepository/IUnitOfWork pattern with Ninject. It should ideally work generically for whatever application is using the code, whether is ASP.Net, WCF or something else.

Say I have a GetCustomer() method on my ICustomerRepository that returns a Customer object. Do I need it to really return an ICustomer object that gets passed back from that method so if I switch from Linq To SQL to say SubSonic it's not a problem? I believe I do
