I love the "Goto Implementation" shortcuts. It's awesome when working with interfaces.

The Peek Definition is also very useful, same goes for the Unit Tests console and the Alt-Enter common shortcut for applying the refactoring suggestions. Review collected by and hosted on G2.com.

I really dislike the performance penalty. Visual Studio gets really slow, specially on bigger solutions. Review collected by and hosted on G2.com.

ReSharper is by far my favorite add-on for Visual Studio. In fact, I think it foolish to ever code without it. Enhanced IntelliSense, code completion, and sophisticated code clean up tools that even highlight potential code issues while you code make ReSharper a must have in the toolbox of any serious C# or JavaScript developer utilizing any given version of Visual Studio.

ReSharper has a lot of features, and those features require quite a bit of overhead. The only time I wouldn't recommend installing ReSharper is on a low-end development environment. As far as the functionality is concerned, I would really like to see the support for JavaScript IntelliSense improved, especially for AMD modules (such as RequireJS.)
