Observer design pattern in .NET

Using Delegates and events we can implement observer design pattern in .net easily.
Delegates and events provides a new and powerful means of implementing the Observer pattern without developing specific types dedicated to support this pattern. In fact, as delegates and events are first class members of the CLR, the foundation of this pattern is incorporated into the very core of the .NET Framework.
