title: what is the name of the app.config of a winforms app? and how can i know that the app loaded that app.config?
body: <p>well i basically cant add an app.config file to my win forms project.<br>
  and i dont know if the application actually uses it or no.<br>
  i used "Add" > "New Item" > "Application Configuration File" but well i dont know if the app reads the data from the file or no.<br>
  so how can i know that the app actually reads that file?<br>
  thanks</p>
