The beta version 2.0 of Resharper is available. I've used and been impressed by Resharper. Just over a year ago, I was coming back to VS.NET, having been using Eclipse for a while. I was amazed how far behind the game Visual Studio was in support for refactoring. Version 2.0 of Resharper includes a built-in tool for running unit tests à la Test Driven .NET. Intriguing.
