IDuplexContextChannel Interface

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

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

public interface IDuplexContextChannel : IContextChannel, 
	IChannel, ICommunicationObject, IExtensibleObject<IContextChannel>

The IDuplexContextChannel type exposes the following members.

  NameDescription
Public propertyAllowOutputBatchingGets or sets a value that instructs to store a set of messages before giving the messages to the transport. (Inherited from IContextChannel.)
Public propertyAutomaticInputSessionShutdownGets or sets a value that indicates whether the input session is shutdown automatically.
Public propertyCallbackInstanceGets or sets the instance context associated with the duplex message exchange.
Public propertyExtensionsGets a collection of extension objects for this extensible object. (Inherited from IExtensibleObject<T>.)
Public propertyInputSessionGets the input session for the channel. (Inherited from IContextChannel.)
Public propertyLocalAddressGets the local endpoint for the channel. (Inherited from IContextChannel.)
Public propertyOperationTimeoutGets or sets the time period within which an operation must complete or an exception is thrown. (Inherited from IContextChannel.)
Public propertyOutputSessionGets the output session associated with the channel, if any. (Inherited from IContextChannel.)
Public propertyRemoteAddressGets the remote address associated with the channel. (Inherited from IContextChannel.)
Public propertySessionIdReturns an identifier for the current session, if any. (Inherited from IContextChannel.)
Public propertyStateGets the current state of the communication-oriented object. (Inherited from ICommunicationObject.)

  NameDescription
Public methodAbortCauses a communication object to transition immediately from its current state into the closed state. (Inherited from ICommunicationObject.)
Public methodBeginClose(AsyncCallback, Object)Begins an asynchronous operation to close a communication object. (Inherited from ICommunicationObject.)
Public methodBeginClose(TimeSpan, AsyncCallback, Object)Begins an asynchronous operation to close a communication object with a specified timeout. (Inherited from ICommunicationObject.)
Public methodBeginCloseOutputSessionBegins an asynchronous operation to close an output session on the client that has a specified time out and state object associated with it.
Public methodBeginOpen(AsyncCallback, Object)Begins an asynchronous operation to open a communication object. (Inherited from ICommunicationObject.)
Public methodBeginOpen(TimeSpan, AsyncCallback, Object)Begins an asynchronous operation to open a communication object within a specified interval of time. (Inherited from ICommunicationObject.)
Public methodClose()Causes a communication object to transition from its current state into the closed state. (Inherited from ICommunicationObject.)
Public methodClose(TimeSpan)Causes a communication object to transition from its current state into the closed state. (Inherited from ICommunicationObject.)
Public methodCloseOutputSessionCloses the output session on the client associated with the duplex channel.
Public methodEndCloseCompletes an asynchronous operation to close a communication object. (Inherited from ICommunicationObject.)
Public methodEndCloseOutputSessionCompletes an asynchronous operation to close an output session on the client.
Public methodEndOpenCompletes an asynchronous operation to open a communication object. (Inherited from ICommunicationObject.)
Public methodGetProperty<T>Returns a typed object requested, if present, from the appropriate layer in the channel stack. (Inherited from IChannel.)
Public methodOpen()Causes a communication object to transition from the created state into the opened state. (Inherited from ICommunicationObject.)
Public methodOpen(TimeSpan)Causes a communication object to transition from the created state into the opened state within a specified interval of time. (Inherited from ICommunicationObject.)

  NameDescription
Public eventClosedOccurs when the communication object completes its transition from the closing state into the closed state. (Inherited from ICommunicationObject.)
Public eventClosingOccurs when the communication object first enters the closing state. (Inherited from ICommunicationObject.)
Public eventFaultedOccurs when the communication object first enters the faulted state. (Inherited from ICommunicationObject.)
Public eventOpenedOccurs when the communication object completes its transition from the opening state into the opened state. (Inherited from ICommunicationObject.)
Public eventOpeningOccurs when the communication object first enters the opening state. (Inherited from ICommunicationObject.)

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.
