Esempio
Nell'esempio di codice seguente viene illustrato l'utilizzo di MessageContractAttribute per controllare la struttura della SOAP envelope per il messaggio di richiesta e il messaggio di risposta, nonché l'utilizzo di MessageHeaderAttribute per creare un'intestazione SOAP per il messaggio di risposta e di MessageBodyMemberAttribute per specificare i corpi dei messaggi di richiesta e di risposta. Nel codice è contenuto un esempio di ogni messaggio quando viene inviato.
