The Accordion control requires you to include System.Windows.Controls.Layout.Toolkit.dll, System.Windows.Controls.Toolkit.dll and System.Windows.Controls.dll if you're using it with Silverlight 2.

According to the release notes, it was new in the March 2009 toolkit release.

It must be on Silverlight 2 Toolkit July.
