Příklady

Následující příklad kódu ukazuje použití MessageContractAttribute k řízení struktury obálky SOAP pro zprávu požadavku i zprávu odpovědi a použití MessageHeaderAttribute obou (k vytvoření hlavičky SOAP pro zprávu odpovědi) a MessageBodyMemberAttribute (k určení těla žádosti i zprávy odpovědi). Příklad kódu obsahuje příklad každé zprávy při odeslání.
