The Auction Web application sample uses a Web service to publish the item listing for the Auction Web site. Web services are XML-based components for the exchange of information between computer applications over the Internet. Because they are governed by a concise set of XML-based standards, Web services are building blocks that allow applications on different computers to interact over the Internet, regardless of platform or language.
This sample might require some optionally installable components. If you encounter errors or cannot find user interface options when you run the sample, ensure that you installed the appropriate optional components.
The Auction Web service demonstrates these benefits by complying with the Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL), and Web Services Interoperability (WS-I) standards.This sample has a dependency on the Auction Web application sample. In order to run the Auction Web service, the Auction Web application sample must be running first.
