Developing a component which can be used to communicate between a Windows desktop application and a web based application is a daunting task in the past. We need to create a windows socket, develop the HTTP protocol module and send HTTP commands over the socket to the web server.

The emergence of web service technologies made the life of the developer easy as this is an HTTP communication framework which can be easily sited to the business requirements of any customers. This framework will enable the developer to easily develop routines that can communicate between desktop (or a web application) and  web application so that they can exchange messages easily which was otherwise difficult using traditional mechanisms like row windows sockets.

In this video tutorial, I will guide you on how to develop a C#.NET web service and call this web service from a windows based application. The tutorial will also show you how to create a web service using VS 2005, add a web service method, how to create the proxy class and how to use this proxy class in the windows application so as to communicate with the web service.
