Scott Guthrie on Expression Blend 2.5
As a follow-up to his introduction to Silverlight 2, Scott Guthrie just posted a great article on using Expression Blend 2.5 to create Silverlight 2 applications.
I really like Blend, but I wish the Xaml editor had intellisense and a few other niceties that we as developers have come to rely on. Of course, that's not its primary target audience :)
Some interesting tidbits in Scott's post include data binding and how to check for design-time vs run-time.
