I created a new WCF Application. It has a svc file & a code behind, When I try to debug (F5) then I see the following.

Why there are different behavior? I do not want to use Test Client, how to disable it in the app so that it would not come again.

Open your project properties, go to the Debug tab, under start options you will see something like
/client:”WcfTestClient.exe”

delete that line.

For a WCF Service Application and WCF Workflow Service Application you need to modify the .csproj.user file. A full write up can be found here.

The key part is

    <WebProjectProperties>
      <EnableWcfTestClientForSVC>False</EnableWcfTestClientForSVC>
    </WebProjectProperties>
