title: How to Determine Which C# Settings File Is Being Used
body: <p>The Settings.settings  file that's part of my C# application has the following <code>User</code> entry. It is called selected_device_idx; is an <code>int</code>; and its value is set to -1. </p>
  
  <p>Yet, during startup, when I fetch this value, it is set to another value, 5.</p>
  
  <p>I am using this to fetch the value</p>
  
  <p><code>int temp_selected_device_idx = (int)Properties.Settings.Default["selected_device_idx"];</code></p>
  
  <p>How can I determine where the origin of this entry?</p>
