The System.Runtime.Remoting.Proxies namespace contains classes that control and provide functionality for proxies. A proxy is a local object that is an image of a remote object. Proxies enable clients to access objects across remoting boundaries.
One of the most important classes of the System.Runtime.Remoting.Proxies namespace is the RealProxy class, which provides the base functionality for all remoting proxies, and can be used to create custom proxies.
