As you can see, creating and using Web Services is very easy. In my own Web applications I have already saved countless hours and days by using Web Services rather than the techniques of old.
In addition to the Health Tip service that I told you about, I have made available the Credit Card Validator service for you to experiment with. To discover and use this Web Service go to http://www.UsingAsp.net/CardService/WebService1.asmx?SDL. And if you come up with your own Web Services please e-mail me. I would love to try them out and take a look.
