title: WPF Maximized Window bigger than screen
body: <p>When creating a WPF window with <code>AllowsTransparency="True" WindowStyle="None"</code> and maximizing it via <code>this.WindowState = WindowState.Maximized;</code> the Window gets bigger than my screen.</p>
  
  <p>When setting <code>AllowTransparency="False"</code> i have a border around my Window, but the window won't get bigger than my screen.<br/>
  In my Case I have a 1920x1080 screen and the window becomes 1934x1094.<br/>
  On my 1280x1024 screen the window will become 1294x1038.<br/>
  The Window will become still as big as this, whether or not AllowTransparency is enabled or not, yet with it disabled it works properly.</p>
  
  <p>Setting AllowTransparency before maximizing doesen't work and throws an InvalidOperationException.</p>
  
  <p>How to get a WPF window without a Windows-style border, but yet to maximize properly?</p>
