Microsoft Silverlight will reach end of support after October 2021. Learn more.

Defines the interface that a channel must implement to both send and receive messages.

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

Syntax

'Declaration
Public Interface IDuplexChannel _
    Inherits IInputChannel, IOutputChannel, IChannel, ICommunicationObject
public interface IDuplexChannel : IInputChannel,

The IDuplexChannel type exposes the following members.

Properties

  Name Description
Public propertySupported by Silverlight for Windows Phone LocalAddress Gets the address on which the input channel receives messages. (Inherited from IInputChannel.)
Public propertySupported by Silverlight for Windows Phone RemoteAddress Gets the destination of the service to which messages are sent out on the output channel. (Inherited from IOutputChannel.)
Public propertySupported by Silverlight for Windows Phone State Gets the current state of the communication-oriented object. (Inherited from ICommunicationObject.)
Public propertySupported by Silverlight for Windows Phone Via Gets the URI that contains the transport address to which messages are sent on the output channel. (Inherited from IOutputChannel.)

Remarks

The IDuplexChannel interface is the union of the IInputChannel and IOutputChannel interfaces. The IDuplexChannel interface does not mandate any correlation between the IInputChannel and IOutputChannel when implemented. This means, in particular, that the contract does not mandate that the sender of messages that are received through the IInputChannel is equal to the recipient of messages sent through the IOutputChannel.
