Adding to the toolbox was not handled by the installer. I went through the process of creating a new tab and browsed to the ComponentArt.Win.UI.Input.dll in the assembly folder for wpf/core. VS threw an error saying it could not load file or assembly 'WPFToolkit, Version 3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35. Not even sure why it needs that. I do have the WPF toolkit installed, just not the version it is looking for. I have 3.5.50211.1. My particular project is actually a Outlook VSTO add-in, but I also tried creating a WPF Application with the same results.
Any ideas on how to get the WPF toolbox items installed?
