Progress Bar performance note

And yet another reminder: if you are using the indeterminate ProgressBar built into the Windows Phone platform, please follow this instructions to make sure you have a smooth, fluid user interface experience. You need to use a special workaround to offload the animations to the compositor thread and remember to toggle IsIndeterminate property back to false when you no longer need it.

This is super important because so many applications are doing potentially heavy processing when they are showing a progress bar like this. The performance issue is not evident in the emulator as much as on actual Windows Phone 7 devices by the way.
