ReSharper (R#) is a tool that I use, love and recommend for anyone who uses Visual Studio. The immediate benefits that it brings and the sheer productivity boost that you gain from using it makes Visual Studio a pleasure to use. I have been using R# for about 2 years now, and keep discovering new gems every now and then, from other R# fans. It compliments Visual Studio so well, sometimes you don’t notice that you are actually using R#.
