title: How to center a WPF app on screen?
body: <p>I want to center my WPF app on startup on the primary screen. I know I have to set myWindow.Left and myWindow.Top, but where do I get the values?</p>
  
  <p>I found <code>System.Windows.Forms.Screen.PrimaryScreen</code>, which is apparently not WPF. Is there a WPF alternative that gives me the screen resolution or something like that?</p>
