This tool integrates smoothly and allows you to work with very big projects.

Personally, I'm a big fan of ReSharper. And while I originally grabbed it for its refactoring support, unit testing augmentations, and its huge amount of other additional UI helps, tweaks, and productivity boosts, one of the things I love the most about ReSharper is its support for templates that make it so much easier for me to quickly code repetitive tasks.

In fact, I use ReSharper's templating functionality all the time when creating new repositories and when creating individual methods within those repositories - because ReSharper's support for "surround-with" templates gives me the ability to easily tackle some custom considerations around caching that I leverage pretty heavily in many repository methods.

If you haven't picked up on my enthusiasm, let me make it obvious: I love using ReSharper 5. The seamless code inspection and navigation add remarkable gains in productivity, and the new ASP.NET MVC support is a much-welcomed bonus. ReSharper is the add-in that turns the Visual Studio 2010 dial to 11.

JetBrains tags ReSharper as "The Must-Have Productivity Tool for .NET Developers," and I emphatically agree. From the continuous code assistance and analysis to its templates and refactoring abilities, ReSharper is the premier Visual Studio extension any serious .NET developer should obtain.
