A KeyedObjectBase can belong to only one KeyedObjectCollectionBase at a time, this is their primary collection. Inheritors subclassing KeyedObjectBase may use this property in exposing their own subclass of KeyedObjectCollectionBase offering additional capabilities.
Customarily, the base class implementations of the OnAddedToCollection and OnRemovedFromCollection methods are responsible for detaching this object from its old collection, and attaching it to its new collection.
