Part 1 shows you how to create a WPF application using VS2008.
Part 2 shows you how to use Blend to style a WPF application created with VS2008; see how you can seamlessly go back and forth between the two tools to get the best out of a developer (intellisense, code wiring, etc.) and designer ( styling, templating) tools for creating WPF applications.
