Public Interface IAttachedPropertyStore


An attachable member is typically implemented and used as an attachable property. The term "attachable member" provides for the possibility that a technology also defines a system for attachable events. As an item in a property store, an attachable event stores a reference to the handler that is assigned through attachable member usage. An attachable event in XAML can use the same store as the attachable properties do, even if the attachable event is not truly a property to the underlying type system or as it is considered in real-world use.
