Jet Brains have announced ReSharper 7.1: a considerable update to the powerful .NET
developer productivity tool for Visual Studio. They invite you to download ReSharper 7.1 and take it for a free 30-day trial. I urge you to try this excellent Visual Studio add-on. Here is their announcement:

Following this update, ReSharper 7 brings even more value to all .NET developers, such as more ways to refactor, inspect, clean up, review and generate code. Feature highlights of ReSharper 7 now include:

Full integration with Visual Studio 2012 while maintaining support for Visual Studio 2005, 2008, and 2010.

Performance and bug fixes: Since releasing version 7.0 this summer, we have fixed over 300 performance problems and bugs.

New code inspections and contract annotations for a more robust .NET code quality analysis. Sharing ReSharper code inspection results with teammates has been streamlined as well for the purposes of code review.

Improved tooling for .NET code maintenance
including the top requested Extract Class refactoring that helps
decrease code complexity, as well as a way to remove unused assembly
references across the entire solution.

Enhanced code formatter: We have implemented some
of the most demanded code formatter improvements so far. For example,
ReSharper 7.1 is able to format XML doc comments and chained method
calls.

Additional code exploration features helping visualize hierarchies of polymorphic members and CSS styles.

An extended and fine-tuned code generation toolset.

In terms of support for specific technologies and frameworks, ReSharper 7 is on the cutting edge as well, providing:

Support for VB.NET refined with the Extract Class refactoring, new quick-fixes and improved IntelliSense.
