Thanks for everyone who came out to MIX and went to the talk. If you didn't get a chance, or want to see it again :), the video has been posted:https://channel9.msdn.com/events/MIX/MIX11/MED12. I've attached the slides below. For what it's worth, I hid a couple redundant slides right before the presentation started in order to keep the presentation on time, I've left them in the attached deck.
Finally, I mentioned Uservoice as a way to send feedback but forgot to provide a URL -- it's http://dotnet.uservoice.com/forums/4325-silverlight-feature-suggestions (or just search for "user voice Silverlight"). Thanks for your feedback!
