We (patterns& practices group @ MS) are currently working on the planning process for Offline Application Block version 2. If you have played with this block...
- Please give us details on what was easy and What specific challenges did you face when using this block?
- Did you create any work-arounds to overcome limitations of the block?
- Did you build or see real world app built using this block? Can you share the design details of that app (if you have one?)
- When you programmed against the OAB API, what was easy, what would you like to change?
- Did you create any extensions for this block?
- Anything else would you like to share…I am open for suggestions.

Thanks for your time!
