Sometimes I envy Ron Jacobs. On a recent ARCast he talked with Daniel Cazzulino about the Mobile Client Software Factory. From the discussion it sounds like this guidance package greatly simplifies mobile development and I could see this being incorporated into future versions of the Compact Framework.
One cool thing they discuss is that they had to rework the Object Builder components to remove the realtime reflection from the Dependency Injection pattern that it uses.
The biggest surprise was that when Ron asked what is next from his guest, the answer had nothing to do with mobile development. It seems that they are working on a requirements gathering tool to initially be used within P&P, but you can be it will become publicly available. Stay tuned!
