Service Web role in windows azure application and how to use the WCF Service in
an outside application.
WCF Service Role enables us to create
WCF service and host in Windows Azure. In this article, we will create a WCF
Service Role and host on local development fabric and consume in a console
Follow the steps given below to

return string.Format("The square of a number is:
Modify web.config file of WCF as shown below:
<transport clientCredentialType="Windows" />

After modifying the above files, press F5 to debug and run your application:
url of service (http://127.0.0.14:81/Service1.svc). The output should something like below:

To call GetSquare() method of the WCF Service (Service1) write the below code:
static void Main(string args)
Service1Client proxy = new Service1Client();
var result = proxy.GetSquare(10);
Now test the application by running (Ctrl + F5) your application:
After reading this article you can easily create WCF Service web role in windows azure application.
