title: What is the WPF equivalent to "System.Windows.Forms.Application.X" for obtaining startup path, app data path, etc.?
body: <p>I'm converting a windows forms application to a WPF application.  Is there a way to obtain things like, Startup Path, User App Data Path, Common App Data Path, etc. without referencing System.Windows.Forms?</p>
  
  <p>Previously, I used <code>System.Windows.Forms.Application.StartupPath</code>, but the <code>System.Windows.Application.Current</code> object doesn't contain the same information.</p>
