Answer:

* This interface is similar to INotifyPropertyChanged, which is to be implemented to notify the WPF/Silverlight framework whenever any changes occur in a collection, like adding an object or deleting an object.
* "ObservableCollection" is a built-in class which implements the INotifyCollectionChanged interface.
