[2005] Add-ons

Thought I'd start a thread regarding recommended add-ons and their locations.
I for one like VBCommenter and VBPowerPack
For windows forms WeifenLuo is good
:thumb:

Any others people would recommend??

I don't know if this would be classified as an add-on, but there's the Web Service Software Factory

If you are viewing 2003 web apps you'll need this add-on as the structure changed in 2005
