Using the Sync Framework on Windows Phone 7
For a mobile platform, like Windows Phone 7, you may be required to allow an application to work even when there’s no data connection available. Doing so is not that easy.

Luckily Microsoft offers the Sync Framework which makes it easier for you to accomplish this by taking much of the required plumbing out of your hands completely.
