I have a new WCF Service Application, when I hit F5 to debug, the WCF Test Client always comes up, but I would like to disable it since I am using soapUI to test instead.
Old thread but found it while I was suffering the same frustration with VS2013. If you run the project (F5) with the (yourProject)\svc.cs file open in the VS editor then the WCF Client starts. If you hit F5 with any other file as the selected and focused file in the VS editor then IIS and the normal first web page starts. Very simple when one knows.
