Property Value

true if this method receives a request message and returns no reply message; otherwise, false. The default is false.

Use the IsOneWay property to indicate that an operation does not return a reply message. This type of operation is useful for notifications or event-style communication, especially in two-way communication.

If the IsOneWay property is set to false (the default), even methods that return void result in a reply message. In this case, the infrastructure creates and sends an empty message to indicate to the caller that the method has returned.

IsTerminating corresponds to the IsOneWay property in the Windows Communication Foundation (WCF) programming model.
