TAILIEUCHUNG - Foundation Silverlight 3 Animation- P5

Foundation Silverlight 3 Animation- P5: Silverlight has really come a long way since I started using it. It’s kind of interesting to look back a mere two years (roughly) and think about how the workflow has changed. Of even more interest is the staggering speed at which new features are being added.
