WPF controls inherit DependencyObject class. See: MSDN

For business entities, you could still implement INotifyPropertyChanged.

INotifyPropertyChanged.

It's in System.ComponentModel

A small trick when using this interface, when you implement it with an empty delegate you don't have to check if the event is null every time you raise it.

public event PropertyChangedEventHandler PropertyChanged = delegate { };
