Just finished WPF Productivity Playbook on PluralSight.
Lots of smaller productivity details I didn't know in WPF, as well as examples of several other things you can do with WPF.
Very interesting, and very well presented. My only complaint would be that there are no captions.
Got to say that the more I learn about it, the more I like WPF. Too bad that MS seems to be phasing it out…
