What's going on in PAG about smart clients? Composite UI Application Block (CAB) is coming!
Note: this entry has moved.
As Eugenio and Edjez mentioned, the second community drop of CAB is around the corner. What you'll find in CAB is basically what's missing the raw widget framework of .NET (a.k.a. WinForms): support for reusability, life cycle management and shared state and events at the use case level, pluggable modules, injection of dependencies between components, and a very powerful loosely coupled event system/broker (among other things). Here's the team, in all its glory, after finally getting an official war room:
The war room has been substantially improved with a reorganization we did yesterday. I'll post more pictures later, but much more happy with the new layout :)
