The class elements in the System.Net.WebSockets namespace that are supported on Windows 7, Windows Vista SP2, and Windows Server 2008 are abstract class elements. This allows an application developer to inherit and extend these abstract class classes and class elements with an actual implementation of client WebSockets.
