title: Why doesn't app.config get added after installing from windows installer?
body: <p>I have a Windows application developed using Visual Studio 2008 (C#).
  It has a app.config file, where various configuration related information are kept. After creating an installer for the project and installing it, there are no app.config file being copied to the installed directory. However, the functionalities that rely on settings in this file seem to work. </p>
  
  <p>Now one of these settings is a database connection string, which obviously needs changing when installed in a different PC. My question is, how to have the app.config file available with the Setup file so that it can be configured later?</p>
