CodeRush and
Refactor! are 2 very powerful VS.NET add-ins that let you program faster. They are made by Developer Express, which is a software company that I have had nothing but incredible dealings with over the years in the Delphi area. As a matter of fact, I used CodeRush for about a year on Delphi way back in the day (maybe 1998?). Even though Mark Miller is the lead man responsible for these products, I'll still use it. (Just kidding, Mark!). In all seriousness, Mark is one of those unique developers who has the passion, vision and technical chops to back it up. I've also known Mark for years from the BorCon speaker circuit. I would highly recommend paying attention to whatever he does, because he does things right.
CodeRush is integrated into the IDE, "bringing you new ways to look at code, new ways to generate code, new ways to navigate through code, and new ways to create your own extensions to your development environment." It is very configurable. There is also a nice training window that will help remind you of what keystrokes to press to generate code. Once you have the keystrokes mastered, you can turn it off.
Refactor! Pro is just unbelievable. It provides over 50 refactorings built-in that work with C#, VB, and C++. At the heart of this product is the mindset that you should never lose workflow with modal dialogs. The result is a thing of beauty, with some of the best eye candy out there. Beauty is fine, but I really want a tool that doesn't miss refactorings, and this tool has proven incredibly reliable on that side as well.
