Creating and Accessing XML Web Services

  • Web Services Description Language (Wsdl.exe) is a tool used to generate code for XML Web services and Web service clients from WSDL, XSD schema files, and discovery documents.
  • Use the XML (Extensible Markup Language), SOAP (Simple Object Access Protocol), XSD (XML Schema Definition), and WSDL (Web Services Description Language) protocols to create a Web service.
  • Use MessageName property to implement two Web methods with the same name and ensure that each of these two Web methods is uniquely identified when it is called separately.

  • Use the CacheDuration property of the WebMethod attribute to specify the number of seconds for which the response should be held in the cache.
  • Use the Namespace property of the WebService attribute to specify the namespace of a proxy generated by Visual Studio .NET 2005.
  • Use the BufferResponse property of the WebMethod attribute to serialize the Web method response into a memory buffer until the response is completely serialized and returned back to the Web service clients over the network.
