Remarks
Silverlight allows you to extend System.ServiceModel.IExtensibleObject<T> objects (the System.ServiceModel.IContextChannel class) by adding a new state or behavior by using its extensible object pattern. The extensible object pattern is used in Silverlight to either extend existing run-time classes with new functionality or to add new state features to an object.
