Some of the controls contained in the System.Windows.Controls namespace documentation are available with the Silverlight runtime, others are only available in the Silverlight SDK. For a list of the controls included in the Silverlight SDK, see Controls by Function. When you use a control from the Silverlight SDK you will need to add a reference to the assembly and include the appropriate XML namespace mapping in XAML.
