Review the SOAP information, a lot of interesting stuff is listed on this page. We will be examining how web services work and how to use SOAP calls for communication in a later tutorial. Click on the button labeled “Invoke”.

Our web service will generate XML containing a string type with the value of “Hello World”. Your browser will display the XML like this.

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">Hello World</string>

Tempuri.org is a namespace that can be used in development and is the default when a namespace one has not been specified. We will explore namespaces in a later tutorial.

Congratulations you have created your first, rudimentary web service.
