Ken,
I have purchased AppDev courseware that you authored and presented, attended VSLive Dallas a couple of years ago, and currently am an AppDev OnDemand subscriber.
I have been studying books and on-line resources about WPF in C# for about six months now but when your content was recently released I jumped into it with great anticipation since I know the value of your teaching. I was not disappointed. To the contrary, I found your examples so far to be the best most practical and easiest to follow and find useful of any content I've studied.
Thanks for developing the courses you present. You are clear, well organized, easy to listen to, andeverything I've sat under where you were presenting has delivered the maximum bang for the buck.
