Jennifer,
This and all other screencasts are awesome! Will you be able to share with the community the source code you have used in the demonstrations either in your blog or through the Channel 9 website? This will help us follow the code while watching the video.
Edit: I guess I was too focussed on the code, and, the output from the console apps!! I later noticed that the sample was from the VS 2008 Training Kit, was easy to download and walk through!
Cheers,
