XML Web services provide a way for applications to exchange data and processing capability. Typically, an XML Web service is a dynamic-link library (DLL) that resides on a Web server and whose methods can be called over the Internet. In this scenario, a client application communicates with an XML Web service by sending and receiving SOAP messages over Hypertext Transfer Protocol (HTTP).
In this article, we will demonstrate how to create, deploy, and access an XML Web service using Microsoft® Visual Studio® .NET. First, we'll set up Internet Information Server (IIS) on the Web server hosting the XML Web service.
