We’ve been working on a little research project recently with WPF and created a small (and hopefully handy) application where you can list your contacts synchronized from Microsoft CRM. We store the offline data in a SQL 2005 Compact Edition database and we access the data using Genome.
To make the experiment more exciting we involved a designer in the project, not only to design a cool UI using the features of WPF, but mainly to see how the collaboration between designer and developer works in reality.
