OneWayBindingElement Class

Enables packet routing and the use of one-way methods.

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

public final class OneWayBindingElement extends BindingElement implements IPolicyExportExtension

To enable packet routing a one-way conversion layer is required, which this class provides. This class is a binding in the stack of bindings that performs a message-level shape change called OneWayBindingElement. This shape change can take a IDuplexSessionChannel or a IRequestChannel and expose it as a IInputChannel, or conversely it can take a IDuplexSessionChannel or a IRequestChannel and expose it as a IOutputChannel. A user can create a custom binding that layers this binding over a session-aware or request-reply transport to make it packet routable.

This class is also useful when you want to expose one-way methods in a more native fashion. More transformations can be applied over this layer, such as Composite Duplex and Reliable Messaging.
