Remarks

When programming with .NET, this class is hidden and developers should use the System.Collections.Specialized.NotifyCollectionChangedEventArgs class.

NewStartingIndex will contain the following values, depending on the Action being reported in the event data.

Action	Value
Add	The index of the newly added item.
Move	The index of the newly added item. Because a Move can logically be considered a virtual Remove followed by a virtual Add, the index reported here might already be adjusted for the virtual Remove.
Remove	-1
Replace	The index of the replaced item.
Reset	-1

Note that this value is signed. This enables the -1 value cases.
