After completing this chapter, you will be able to
Use and implement the INotifyCollectionChanged interface.
Use the ObservableCollection(T) class.
Use the ICollectionView and CollectionView derived classes.
Bind collections to WPF and Silverlight controls.
The INotifyCollectionChanged interface is an interface that exposes a CollectionChanged event. The CollectionChanged event is raised whenever the collection is changed, such as when it is cleared, removed, or added to. The INotifyCollectionChanged interface is implemented by the ObservableCollection(T) class, which you learn about later in this chapter.
