When is a new added object reflected in de EntitiesContext?

example:

The application is a Northwind extension with EDM applied

when I a add a new customer to the entities context I don's see the new customer in de list until I do a SaveChanges to the database an do a refresh of create a new Entitiescontext object.

Customers lCustomers = new Customers();

Console.WriteLine(_Entities.Customers.Count<Customers>());

_Entities.AddToCustomers(lCustomers);

Console.WriteLine(_Entities.Customers.Count<Customers>());

Both Writeline calls display 91 in the console output? Why

Is there any way to add an Entity from the Model Browser and have it derive from an Entity or class that is just used as a base class and doesn't relate to the database at all?  For instance, I would like all my Entity objects to derive from MyEntityBase, which defines some validation methods.  Is something like this possible?  when trying to set "Base Type", it only gives me a choice of entities that i have created in the Model Browser and if I try to create my base entity without assigning a table, it gives me a "No Mapping Specified" error.
