WF toolbox is broken after resetting toolbox in VS 2010

I am playing with WF 4.0.

I accidently pressed "Reset Toolbox" in a WF 4.0 project. This broke the toolbox.

All the Flow chart and messaging activities were gone and I could not add them back manually. Only the procedural tab activities remained.When I tried to add the missing activities manually (choose Items) I could not find them under the activities tab.

To solve this issue simply delete the .tbd files under:

XP:   %USERPROFILE%\Local Settings\Application Data\Microsoft\VisualStudio\10.0
Vista: %USERPROFILE%\AppData\Local\Microsoft\VisualStudio\10.0

Enjoy
