Inheritance diagram for Loyc.Collections.Impl.DictionaryWithChangeEvents< K, V, TDictionary >:

Remarks

A dictionary wrapper that provides ListChanging and ListChanged events. You can also implement custom behavior by overriding its methods.

The Keys and Values properties return ICollection, but this class assumes that mutating these collections is not allowed (mutating them is not allowed, for example, by Dictionary{K,V}). Therefore change notification is not implemented for changes to these collections; these properties simply return the original collection.
