Remarks
IVectorChangedEventArgs is specifically used for the VectorChanged event of the IObservableVector<T> interface, via the VectorChangedEventHandler delegate.
.NET developers can get instances of this interface via handling the VectorChanged event from an IObservableVector instance. Even though the remainder of the collection support for IObservableVector uses language projections that change IVector<T> APIs to IList<T> APIs, the VectorChanged event, its delegates and its event data aren't changed by the projection and so "Vector" (as opposed to "List") remains in the API names.
