IExtensibleObject<T> Interface

Definition

Namespace:

System.ServiceModel

Assembly:

System.ServiceModel.Primitives.dll

Package:

System.ServiceModel.Primitives v8.1.1

Source:

IExtensibleObject.cs

Enable an object to participate in custom behavior, such as registering for events, or watching state transitions.

C#

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

Type Parameters

T

The type of the extension class.

Derived

System.ServiceModel.ClientBase<TChannel>.ChannelBase<T>

System.ServiceModel.IClientChannel

System.ServiceModel.IContextChannel

System.ServiceModel.IDuplexContextChannel

System.ServiceModel.InstanceContext

System.ServiceModel.IServiceChannel

System.ServiceModel.OperationContext

System.ServiceModel.ServiceHostBase

Remarks

Implement IExtensibleObject<T> to enable aggregation of extensions.

For example, if you are implementing a TreeNode class and want to allow external code to add annotations and methods to some instances of TreeNode, you can have TreeNode implement IExtensibleObject<TreeNode>. This enables code that uses TreeNode to add objects that implement IExtensibleObject<TreeNode> to the Extensions collection.

There are four extensible objects in Windows Communication Foundation (WCF):

• System.ServiceModel.ServiceHostBase

• System.ServiceModel.InstanceContext

• System.ServiceModel.IContextChannel

• System.ServiceModel.OperationContext

For a discussion about how to create extension to work with these objects, see Extensible Objects.
