RequestContext.Reply Method (Message, TimeSpan)
When overridden in a derived class, replies to a request message within a specified interval of time.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Use when it is acceptable for the current thread to be blocked while it replies to the request message. The thread is blocked up to the specified timeout.
If the application processing must continue without waiting for the reply to complete, use the asynchronous method. This method receives notification, through a callback, of the identity of the event handler for the operation. The operation is not complete until either a message becomes available in the channel or the time-out occurs.
