Příklady

Následující příklad kódu ukazuje použití WsdlContractConversionContext k přidání vlastní WSDL poznámky do exportovaných metadat pomocí WsdlPortType a Contract vlastnosti. Při exportu operací metoda iteruje popisy operací a vyhledá každou přidruženou System.Web.Services.Description.Operation metodu GetOperation voláním metody .
