C#.Net How To: Test a WCF Service in VS 2010 using wcftestclient.

I am assuming that your WCF web service is already built and ready to test. Please refer my previous post on how to Create a WCF Web Service in Visual Studio 2010

Before proceeding with wcftestclient utility, you must know the URL of your WCF web service. Execute the web service you created and then you will get your WCF web service URL from following screen –

1) Once you get WCF service URL. Start a visual studio command prompt. In windows 7 OS, to start Visual Studio command prompt goto Start -> All Programs -> Microsoft Visual Studio 2010 -> Visual Studio Tools -> Visual Studio Command Prompt (2010)

You will get following command prompt.
