My understanding is that CAB is dead and that a new, Silverlight based product based upon the Composit Application Guidance for WPF and Silverlight, previously codenamed Prism, is being developed and will be a paid-for product rather than a free addition like Cabana. This product will work with DevForce EF.
Whilst I'm not keen on having to pay money for the thing, being only a very small rural school, such an IdeaBlade product will undoubtedly be more successful and importantly, at least for the few who still, hopefully, check on this forum it will be revenue producing and therefore something that IdeaBlade can afford to properly support.
Giving away Cabana and its attendant bits and pieces was, whilst laudable not sustainable, probably due to the perceived or otherwise low DevForce sales pull through.
The big problem with CAB/SCSF and Cabana was their complexity for the small IT shops who have few people and even fewer funds.
My brief look at Prism would suggest it is easier to begin to use albeit with the steeper WPF/Silverlight learning curve.
It will be interesting to see the Silverlight based product to replace Cabana...
