Voorbeelden

In het volgende codevoorbeeld ziet u hoe u WsdlContractConversionContext aangepaste WSDL-aantekeningen toevoegt aan de geëxporteerde metagegevens met behulp van de WsdlPortType en Contract eigenschappen. Bij het exporteren van bewerkingen doorloopt de methode de beschrijvingen van de bewerkingen en zoekt de System.Web.Services.Description.Operation bijbehorende bewerkingen door de methode aan te GetOperation roepen.

    // DocumentElement property.
