Remarks

WCF allows you to extend System.ServiceModel..::.IExtensibleObject<(Of <(T>)>) objects (the System.ServiceModel..::.IContextChannel, System.ServiceModel..::.ServiceHost, System.ServiceModel..::.InstanceContext, and System.ServiceModel..::.OperationContext classes) by adding a new state or behavior by using its extensible object pattern. The extensible object pattern is used in WCF to either extend existing run-time classes with new functionality or to add new state features to an object.
