The Object Test Bench is, in my opinion, one of the lesser known features of Visual Studio 2005. The Object Test Bench provides a way for you to create instances of your classes within the Visual Studio 2005 IDE and then invoke methods on those objects, manipulate their properties and otherwise interact with those objects ... all without writing any code!
I want to thank Ron Jacobs for recommending Camtasia Studio as the screen capture and production application of choice. The fine folks over at TechSmith, the creators of Camtasia Studio, have been awesome in getting me up and running on 64-bit Windows Vista RC1. And a very special thank you to Keith Combs for assisting me with the internal publishing procedure to get the screencast up on wm.microsoft.com.
