Answer 2

You need to set the ResizeMode to NoResize and WindowState to Maximized

  <Window ...    
    ResizeMode="NoResize" WindowState="Maximized">

Answer 3

Simply hook this event handler to the Loaded event of the form, works fine.
Do not apply this stuff in the constructor of the form (which won't work for me).

    private void aWindow_Loaded(object sender, RoutedEventArgs e)
    {
        MaxHeight = SystemParameters.FullPrimaryScreenHeight;
        MaxWidth = SystemParameters.FullPrimaryScreenWidth;
        Width = SystemParameters.FullPrimaryScreenWidth;
        Height = SystemParameters.FullPrimaryScreenHeight;
        WindowState = WindowState.Maximized;
        ResizeMode = ResizeMode.NoResize;
        Left = 0;
        Top = 0;
        Topmost = true;
        ShowInTaskbar = false;

        //throw new NotImplementedException();
    }
