Defines the interface a client channel must implement to exchange messages in a duplex session.

Remarks
A duplex contract requires a session, because a context must be established to correlate the set of messages being sent between the client and the service.
Properties
| AllowOutputBatching |
Gets or sets a value that instructs Windows Communication Foundation (WCF) to store a set of messages before giving the messages to the transport. (Inherited from IContextChannel) |
| AutomaticInputSessionShutdown |
Gets or sets a value that indicates whether the input session is shutdown automatically. |
| CallbackInstance |
Gets or sets the instance context associated with the duplex message exchange. |
| Extensions |
Gets a collection of extension objects for this extensible object. (Inherited from IExtensibleObject<T>) |
| InputSession |
Gets the input session for the channel. (Inherited from IContextChannel) |
| LocalAddress |
Gets the local endpoint for the channel. (Inherited from IContextChannel) |
| OperationTimeout |
Gets or sets the time period within which an operation must complete or an exception is thrown. (Inherited from IContextChannel) |
| OutputSession |
Gets the output session associated with the channel, if any. (Inherited from IContextChannel) |
| RemoteAddress |
Gets the remote address associated with the channel. (Inherited from IContextChannel) |
| SessionId |
Returns an identifier for the current session, if any. (Inherited from IContextChannel) |
| State |
Gets the current state of the communication-oriented object. (Inherited from ICommunicationObject) |
Methods
| Abort() |
Causes a communication object to transition immediately from its current state into the closed state. (Inherited from ICommunicationObject) |
| BeginClose(AsyncCallback, Object) |
Begins an asynchronous operation to close a communication object. (Inherited from ICommunicationObject) |
| BeginClose(TimeSpan, AsyncCallback, Object) |
Begins an asynchronous operation to close a communication object with a specified timeout. (Inherited from ICommunicationObject) |
| BeginCloseOutputSession(TimeSpan, AsyncCallback, Object) |
Begins an asynchronous operation to close an output session on the client that has a specified time out and state object associated with it. |
| BeginOpen(AsyncCallback, Object) |
Begins an asynchronous operation to open a communication object. (Inherited from ICommunicationObject) |
| BeginOpen(TimeSpan, AsyncCallback, Object) |
Begins an asynchronous operation to open a communication object within a specified interval of time. (Inherited from ICommunicationObject) |
| Close() |
Causes a communication object to transition from its current state into the closed state. (Inherited from ICommunicationObject) |
| Close(TimeSpan) |
Causes a communication object to transition from its current state into the closed state. (Inherited from ICommunicationObject) |
| CloseOutputSession(TimeSpan) |
Closes the output session on the client associated with the duplex channel. |
| EndClose(IAsyncResult) |
Completes an asynchronous operation to close a communication object. (Inherited from ICommunicationObject) |
| EndCloseOutputSession(IAsyncResult) |
Completes an asynchronous operation to close an output session on the client. |
| EndOpen(IAsyncResult) |
Completes an asynchronous operation to open a communication object. (Inherited from ICommunicationObject) |
| GetProperty<T>() |
Returns a typed object requested, if present, from the appropriate layer in the channel stack. (Inherited from IChannel) |
| Open() |
Causes a communication object to transition from the created state into the opened state. (Inherited from ICommunicationObject) |
| Open(TimeSpan) |
Causes a communication object to transition from the created state into the opened state within a specified interval of time. (Inherited from ICommunicationObject) |
Events
| Closed |
Occurs when the communication object completes its transition from the closing state into the closed state. (Inherited from ICommunicationObject) |
| Closing |
Occurs when the communication object first enters the closing state. (Inherited from ICommunicationObject) |
| Faulted |
Occurs when the communication object first enters the faulted state. (Inherited from ICommunicationObject) |
| Opened |
Occurs when the communication object completes its transition from the opening state into the opened state. (Inherited from ICommunicationObject) |
| Opening |
Occurs when the communication object first enters the opening state. (Inherited from ICommunicationObject) |
