I've spent some time
looking at the Vertigo WPF reference application Family.Show. It's a really
cool application, while I was playing around with it Rebecca saw it and
immediately wanted it installed on her computer, she's been busy entering data
into it. I hope an open source community forms around it.
The most interesting
thing I found was a presentation by Scott Stanfield at Mix 07, he describes
some of the lessons learnt from building this application. From the sounds of
it the problem domain caused the bulk of the problems. It's certainly a testament
to the design of the WPF that guys who have never used it before can produce
something so stunning and the code is very nicely laid out.
