Learn how to set up and use XML Web Services by using the soap/http in SQL Server 2005 (formerly known as "Yukon"). A related example is also included in the article. To benefit most from this article, you should have a basic understanding of Web services technologies, including HTTP, soap, and WSDL. It includes requirements, HTTP endpoints, creating HTTP endpoin
