Animation in Silverlight/XNA

I've been practicing with the new Silverlight/XNA model but I'm not sure how to go about animating a game character. Anyone kno开发者_运维百科w the best approach to animating in Silverlight/XNA? Would I still use XNA frame-based animation? (I tried this and I was unsure on how to get elapsed time from GameTimer where as GameTime had it as a property)

Thanks
