Summary

In this chapter, you took a fairly high-level overview of SOAP, WSDL, and UDDI. These three technologies are part of the foundation of SOAP. By understanding how they all work, you will be able to develop high-quality Web Services. Coupled with some prior experience reading XML, this chapter provides you with enough information to understand a WSDL file and what a compliant SOAP message for a given WSDL file should look like. When developing SOAP messages that communicate with non-Microsoft toolkits, you will have to know how to read the raw XML messages going between endpoints.

You will rarely program directly against a UDDI data store. More often, you will use the user interface provide by the registrar to register your business and Web Services. This task is made easier through tools provided by Visual Studio .NET. You will learn more about lookup and registration of Web Services in Visual Studio in Chapter 4. For more information on the material covered in this chapter, refer to the resources in Appendix A.
