When writing WCF services, most of us find ourselves writing quick test applications. To give you more time to do what a developer should be doing (adding business value to the project) the Visual Studio team added a WCF test client that can help you reach goals faster.
This is not a very difficult application, but it does the trick and is more than sufficient for simple testing. The WCF Test Client can be found at this location (without the ‘ (x86)’ for x86 machines): C:\Program Files (x86)\Microsoft\Visual Studio 10.0\Common\7\IDE.
Taken from the help:
Windows Communication Foundation (WCF) Test Client (WcfTestClient.exe) is a GUI tool that allows users to input test parameters, submit that input to the service, and view the response that the service sends back. It provides a seamless service testing experience when combined with WCF Service Host.
