Yesterday I noticed that my list of tools to use in Visual Studio was more or less reduced to none. This concerned me since SSIS packages are all tools based and well, I can’t really do much if I can only run a backup database task.
After googling it for a bit, I found the post that explained exactly what to do. The cached toolbox files were screwed up and needed to be regenerated. I started by right clicking and saying “Reset Toolbox” but no luck.
In the end I had to kill all of the tbd files that were created automatically by Visual Studio (more information).
The paths in that post are for Vista and XP, so I found another one that actually defined where to find them in Windows 7 (Visual Studio Application Data Folder).
Make sure to close Visual Studio before trying this or who knows what will happen …
Hope this helps!
