After installing VS 2005 SP1 beta I noticed that all 3rd party icons disappeared from toolbox. Apparently SP1 beta looses icons on install. The situation is more annoying with [DevEx] components because setup won’t repair the situation nor will uninstall/install help (Note: I didn’t check much other vendor’s components, I just noticed that telerik asp.net stuff is installed correctly). Obviously SP1 beta changed something in toolbox entry install process and installer for [DevEx] stuff doesn’t work correctly. You can still create all those entries manually but this process is rather tedious.
The good news is [DevEx] folks already fixed the problem. All you need to do is to download improved ToolBoxCreator tool (a tool that ships with their stuff) that you’ll find here and run it. Simple as that.
