XAML Layout In Depth, by Thomas Claudius Huber is another interesting PluralSight course. It covers Layout in XAML (both WPF and WinRT/UWP).
It mostly covers a tiny fraction of WPF 4.5 Unleashed, but as it has been a couple of years since I read that, the refresher was useful.
The MVVM examples are also interesting, and I liked the use of FluidMoveBehavior – it not only looks much nicer than the regular view, it is also easier to see what happened.
Overall, nice and not too long (about 5 hours).
