It was so easy to test the old fashion .asmx web services from the production servers, since you could just grab the link, put it in a browser and a full fledged test you could run on it.
With the WCF services is not the same. If you just grab the link and open it in a browser, all what you get is a confirmation that the service it’s running properly, and how to use it in the client applications.
Here comes handy the WcfTestClient tool. Create a folder on the server and copy the next files in it from C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE (path may wary, depending what OS/Visual Studio you have installed):
If you get an error related to VirtualTreeGrid assembly, just add the assembly to the GAC (Win+R) and add the path:
Copy the file Microsoft.VisualStudio.VirtualTreeGrid.dll into the same folder where you copied the files mentioned above.
