title: Setting Visibility="Hidden" on WPF Window never shows the window again
body: <p>I have set the <code>Visibility</code> property of the main window to <code>Hidden</code> and added the following in <code>Window_Loaded</code>:</p>
  
  <pre><code>private void Window_Loaded(object sender, RoutedEventArgs e)
      {
          this.Visibility = System.Windows.Visibility.Visible;
      }
  </code></pre>
  
  <p>But it doesn't show up the Window. Any specific reason for this?</p>
