Separator for Menu Item in XAML (WPF, Silverlight)

Trivial task and yet worth mentioning: You want a separator in your XAML based application (WPF or Silverlight)? Use System.Windows.Controls.Separator. In XAML write as follows:

<Menu ...
  <MenuItem ...
     <MenuItem ...
     <Separator />
     <MenuItem>
  </MenuItem>
</Menu>

In C# use:

using System.Windows.Controls;

Menu menu = new Menu();
...
menu.Items.Add(new Separator());
