title: MyApp.exe.config is not being loaded in Winforms application
body: <p>I am using ConfigurationManager.AppSettings[key] to read configuration from MyApp.exe.config. It was all working fine until yesterday. I have tried rebuild clean project, copy output always, readded reference using System.Configuration.
  couple of new configurations added yesterday are missing when tested on developer machine. Seems like its picking up old configs. </p>
  
  <p>In real environment it works fine. just developer machine i cannot spot the difference. I understand there is MyApp.exe.config gets cached. I would like to find out where is it? What is the best way to tackle this issue?</p>
  
  <p>Any help would be appreciated. Thank you</p>
