Your favorite add-in?
Have you voted for the best Visual Studio.Net add-in contest?
What did I vote for? The Reflector Add-in of course. definitely the coolest tool and most useful I've seen yet. And it just got released with a new version too.
What? You didn't know there was one? well there is. And it allows you to see the actually see the decompiled assembly source while debugging inside VS.Net. Very exciting stuff for those who like it low-level.... :)
