Simple examples of hosting the script on a ASPX page with

Extra useful tools for making interacting with webservices:

· With WCF services (and ASMX) you can get the necessary data for SOAP call with WcfTestClient.exe you probably will find here

- "C: \ Program Files (x86) \ Microsoft Visual Studio 10.0 \ Common7 \ IDE \ WcfTestClient.exe"

· Fidler is a usefull tool to show all what is sent and received on the http protocol: http://www.telerik.com/download/fiddler
You can use this tool for discover how to interact with a webservice, by using the service from other applications.
