Thats great, but
.NET Presentation .NET Web Services

• Lets see what .NET is REALLY all about.
• .NET heavily utilises web services
• Web Services are based on W3C open standards
  (HTTP, XML and SOAP)
• Any application that supports these open
  standards can communicate with a .NET
  application locally or remotely

• The browser shows the response given by your web
  service in XML format
• Advantages
• Test your web service locally before deploying it
• Allows external developers to play with your web
  service without having to write a single line of
  code
• Useful for testing and isolating bugs in your
  system.

Your next step
.NET Presentation Conclusion

• Download Visual Studio Express Editionhttp//lab.
  msdn.microsoft.com/express/
• Find or create some web services to interact with
  (Plenty of good examples at www.xmethods.net)
• Write some code that consumes or serves content
  via SOAP and XML
• Publish it on a web site, as an application or
  both!
