title: GetFolderPath(SpecialFolder.ApplicationData) returns empty string
body: <p>I saw many old questions like this but it is not my case.</p>
  
  <p>Asp.net application is running in AppPool (iis in win10) with 'load user profile' enabled.</p>
  
  <p>And nevertheless Environment.GetFolderPath(ApplicationData or LocalApplicationData) returns an empty string. CommonApplicationData returns correct folder.</p>
  
  <p>I ensure that {user}\AppData is exist on disk. </p>
  
  <p>So, question: how can I get not empty string for AppData?</p>
