AutoCompleteBox in Silverlight

Question

I have a Silverlight 3 project I am trying to convert to Silverlight 4. I use the autocompletebox. I cannot find the correct namespace/reference for this in Silverlight 4. Has it moved? What reference do I need? Thanks in advance.

Answer 1

Its in the System.Windows.Controls.Input.dll in the namespace System.Windows.Controls.

This has not changed from 3 to 4.
