ADO.NET 3 - Entity Framework without Persistance Ignorance
Ayende says, "
Here is an interesting discussion about this topic. Apperantly you will not be able to just take any object and persist it using the Entity Framework. You need to either inherit from a base class, or (in the future) implement a set of interfaces. I can't figure out what the reason for that is. It is not as if supporting POCO persistance ignorance is hard or complicate the framework (at least not compare to the issues of the persistance and querying themselves).
One of the goals for NHibernate is that you should be able to develop your application where only the controller has a reference to NHibernate, nothing else. "
Just know that myself, Jeremy Miller, Scott Bellware, Jeffery Palermo, raymond lewallen, Jean Paul Boodhoo and James Kovacs are taking the Entity folks apart about this as we speak (at the Summit) and teaching them about NHibernate.
See Jeffery Palermo's post for details and why you should care.
