Creating and using Web Services

Creating and using Web Services

Over the last few months I've spent a lot of time talking about XML and Web Services and how you can build and consume them. This time we'll look at the new features in Visual Studio.NET and ASP.NET that provide a very easy mechanism for creating Web Services and more importantly the easy mechanism used to consume those same Web Services using the .NET framework's built in support for Web Services.

Web Services promise to bring information into your applications from the Internet in much the same way that browers have made information available to end users. The .Net framework introduces Web Services as an integral part of the architecture, making it very easy to create and consume these services with minimal amounts of code written. In fact, if you read Microsoft's documentation, Web Services are featured as the new component architecture in the distributed age where not only Internet exposure is handled through them but also common reusable business and application services.

The .Net framework abstracts most of the internal logic that handles the remoting details of method calls over the wire and Visual Studio .Net builds support for Web Services directly into the development environment. With all of this in place it becomes almost as easy to call a remote method as it is to call a local method. And that after all is what Web Services are about – making server side logic easily available to client applications.
