Which menu have you used with Silverlight 4 and Silverlight Toolkit 5? Is there a free menu that can be used with this Silverlight version combination? I tried to use SL4PopupMenu, but get the exception

Could not load file or assembly 'System.Windows.Controls.Toolkit, Version=,


Could not load file or assembly 'System.Windows.Controls, Version=,

when I change the reverence version of System.Windows.Controls.Toolkit from 4 to 5. Thank you for help.

Why would you use the SL5 version of the Toolkit with SL4? –  jv42 Mar 14 '12 at 17:01
I don't know. This is a good question. Thank you. –  Julia Mar 15 '12 at 11:00

I suggest you recompile the source code for the menu after updating the SL4 references in the project to SL5. This should get rid of the exception.
