Use this method to check whether a particular persistent object belongs to the current Object Space. If the object passed as the parameter belongs to another Object Space, this method retrieves the same object from the database via the current Object Space.

When implementing the IObjectSpace interface in the BaseObjectSpace class's descendant, don't implement the GetObject<ObjectType> method. It's implemented in the BaseObjectSpace class. The BaseObjectSpace.GetObject<ObjectType>(ObjectType objectFromDifferentObjectSpace) method calls the BaseObjectSpace.GetObject(Object objectFromDifferentObjectSpace) method, which returns null. The latter method is virtual. So, you should override it in your descendant.
