The following shows the XML namespace mapping that you have to specify when you work with styles and templates.

<!-- XML Namespace mapping. -->
xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"

Note   The default templates still specify the vsm: XML namespace mapping for the VisualStateManager element for legacy reasons. You can however, use the VisualStateManager element without specifying the vsm: mapping.

The following XAML show the default styles and templates for the Slider control and the Thumb class.
