Creating ASP.NET Web Services

Using the .NET Framework, it's easy to get a basic service up and running. In just a few minutes and fewer lines of code, you can put together a simple "Hello World" service without any understanding of HTTP, SOAP, WSDL or any of the several technologies that form the basis for web services. In fact, if you're a Microsoft Visual Studio .NET user, all you need to do to create a simple "Hello, World" service is to open a new Visual C# or Visual Basic ASP.NET Web Service project and uncomment the sample code provided by the template.

In this chapter, you'll learn about ASP.NET, the new Microsoft technology for building web applications and services, and how to use the .NET platform and Visual Studio .NET to create some simple web services. We'll also talk about some of the features of .NET that will get you on the road to developing well-documented scalable web service applications. By the end of this chapter, you'll have a solid understanding of how .NET supports web services and how to use the .NET platform to create them. We'll start with the ubiquitous "Hello, World" example exposed as a web service.
