Implementing Web Services and the UDDI

Abstract

There has been a great deal of hype in the business world concerning Web services. You have probably heard all about them recently, you may have read an article about them. The truth is that I have heard as many different explanations for what a Web service is as people I have heard try to explain what it is. This chapter gives you a solid definition (at least, my version) of what a Web service is and a practical overview of how to implement one. This chapter covers how to create a Web service and how to incorporate the code that you already created for the rest of the NorthwindTraders application. It also covers how to access that Web service from another Windows forms application. You will also see you how to create classes based on a Web service using the Web Service Description Language (WSDL) utility that ships with.NET. This chapter does not cover Web service security, which is an extremely large topic, or the many competing standards and organizations pushing for those standards.
