What makes a smartphone application compelling to users? A compelling design, of course, one that not only delivers the benefits that users want, but also keeps them engaged, even entertained, as they navigate its features. Adding animations is a powerful way to not only to engage the users but also make your application fun to use. In this session, you will learn first how to create a time based animation using Microsoft Expression Blend 4 and then invoke them with C# code you write with Visual Studio 2010. You will do this by animating the character of Morton the hamster. And then you will be introduced to more advanced topic by learning to create a frame based animation that displays smoke rising from an active volcano.
