IExtension<T> Interface

Enables an object to extend another object through aggregation.

Namespace:  System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public interface IExtension<T>
where T : Object, IExtensibleObject<T>

Type Parameters

T

The object that participates in the custom behavior.

WCF allows you to extend System.ServiceModel.IExtensibleObject<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.
