IExtension<T> Interface

Definition

Namespace:

System.ServiceModel

Assembly:

System.ServiceModel.Primitives.dll

Package:

System.ServiceModel.Primitives v8.1.0

Source:

IExtension.cs

Enables an object to extend another object through aggregation.

generic <typename T>
 where T : IExtensibleObject<T>public interface class IExtension

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

type IExtension<'T (requires 'T :> IExtensibleObject<'T>)> = interface

Public Interface IExtension(Of T)

Type Parameters

T

The object that participates in the custom behavior.

Derived

System.ServiceModel.Activation.VirtualPathExtension

System.ServiceModel.Description.ServiceMetadataExtension

System.ServiceModel.Discovery.DiscoveryOperationContextExtension

System.ServiceModel.Discovery.DiscoveryServiceExtension

System.ServiceModel.Routing.RoutingExtension

System.ServiceModel.Web.WebOperationContext

Remarks

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.

Methods

Attach(T)	Enables an extension object to find out when it has been aggregated. Called when the extension is added to the Extensions property.
Detach(T)	Enables an object to find out when it is no longer aggregated. Called when an extension is removed from the Extensions property.
