The System.Net.Sockets namespace provides a managed implementation of the sockets networking interface for developers who need to tightly control access to the network. On Windows, the System.Net.Sockets namespace provides a managed implementation of the Windows Sockets (Winsock) interface. On Apple Mac OS X, the System.Net.Sockets namespace provides a managed implementation of the sockets interface based on Berkeley Software Distribution (BSD) UNIX.
The System.Net.Sockets namespace provides a mechanism for real-time duplex communication with remote network resources and enables higher-level APIs to communicate over a bi-directional transport. This also allows an application to interoperate as a client with existing TCP services.
The System.Net.Sockets namespace in Windows Phone has added support for UDP multicast clients.
For additional socket methods for Windows Phone, see SocketExtensions.
