The first third of the talk was about all the normal Silverlight
stuff: Xaml, layouts and simple databinding. It seems
that most things works like expected.
The second part was much more interesting. It was shown how the
MVVM pattern could be used to obatin the one object, one task
paradigm. Then various forms of dependency injection was shown
using nInject and ServiceLocator and/or MEF. It was very clean and
looked pretty easy.
The last part was about Blend and how to get from a picture made
by a graphical designer to a real Xaml GUI. It seems that Blend is
a pretty strong tool for those kind of tasks.
