Note: While I did contribute just 1 of the 100 hacks, I wasn’t paid, so don’t think I’m motivated by money. 
Visual Studio Hacks is the best power-users book about everyone’s favorite IDE that I’ve seen. A few hacks explain little known features, but the vast majority of the book is dedicated to unleashing the power of Visual Studio extensibility. And most of the book covers topics that the standard documentation and references don’t cover.
James also covers a slew of great add-ins. Most of these were created by the developer community and are extremely polished. And they are certainly better than doing things by hand!
The Hacks series from O’Reilly are great for reading when you find yourself with 10 minutes of free time at the doctor’s office or stuck in traffic. You can cover a hack or two, put the book down, and then not have to worry about remembering the state of the book when you pick it back up.
Buy the book at Amazon.
You can preview 5 of the 100 hacks at O’Reilly’s web site.
James has setup the Visual Studio Hacks web site and updates it regularly.
