This concludes the demonstration of how to implement a simple SOA in Visual Studio 2005.
It's important to recognize that at this point you have constructed a distributed application in about 15 minutes with minimal work; a feat that would have taken weeks on older platforms, or hours in Visual Studio 2002/2003.
For more information you can either pick up a book on ASP.NET, Web Services, or introductory SOA books or look for tutorials online. Your local bookstore should carry a decent selection of these books, targeting both general issues as well as specific implementations. On the internet, your best bet is to start with Microsoft's documentation, and then explore the more popular sites geared towards ASP.NET and design.
Learn about more SOA concepts and designs at the .NET SOA Center.
Explore GotDotNet, a site dedicated to .NET; the QuickStarts are especially useful when learning new features.
Visit asp.net, a site dedicated to the environment.
Run through the demonstration again, taking the time to play with the different configuration options available throughout.
Troubleshooting
It has been assumed that IIS and ASP.NET are functioning properly and Visual Studio has been installed correctly. There are many things that can go wrong during this demonstration, however all of them are beyond the scope of this document.
