Vista - How to render multiframe images?

Hello-

Does WinFX have a way to render and play multiframe images (such as
animated GIF's, TIFF's, etc.)? I would like to render an animated GIF
inside a Canvas, but it's not clear how to get it to run through the
frames.

I have seen some discussion of the BitmapFrame class but not any
documentation on how to use it, or even if it would be relevant to this
application.

Any suggestions or code snippets would be appreciated. Thank you!
