Ask anyone who has heard me speak on Test-Driven or Agile development, and you'll hear that I'm a very big fan of the TestDriven.NET add-in for Visual Studio. Jamie Cansdale has done a great job making a great tool that Just Works. May you never Alt-Tab away from Visual Studio to run or view your unit tests again.
After numerous releases of 0.* versions, Jamie has cut the first 1.* version. You can download it from TestDriven.net.
Jamie has added a slightly lengthy survey which you must complete before downloading, but the add-in has saved me so much hassle over time that I had no problem supplying him with the details he's interested in.
It is best described on the website itself: “TestDriven.NET is a free, zero friction unit testing add-in for Microsoft Visual Studio .NET. The current release of TestDriven.NET supports multiple unit testing frameworks including NUnit, MbUnit, csUnit and MS Team System and is fully compatible with all versions of the .NET Framework.” If you haven't seen it in action, take a look at some screenshots and read the quickstart guide.
The fact that TestDriven.NET works with Visual Studio Team System is most welcome. Although unit testing is now fully integrated with Team System (Developer and Tester editions), having the “Run Tests” command available from additional contexts like the code editor is a great time saver.
If you create unit tests for your .NET systems (and of course you are, right?) you should download it now.

P.S. No, I'm not on Jamie's payroll, but for the number of referrals I've given, I should get a percentage of the royalties. What's that you say? It's FREE? ;)
