In this article Steve from the Expression Blend and Design team examines Storyboards, Visual States and SketchFlow animations.
What are these things – are they different ways of doing the same task? When would I use one in preference to another? Do they all work in all project types?
This post will try to answer those questions by describing the animation and control customization tools that are available to you in Expression Blend 3 + SketchFlow, and discussing what jobs each tool is meant to do. I’ll be classifying project types along two independent axes: WPF or Silverlight, and Blend or SketchFlow.
