I had an exchange with G. on the prospects for something like Cabana in the WPF / Silverlight world. I thought I'd share it here in the forum.

I'm sure I had a twitter from Ward saying he was working on a Silverlight equivalent to Cabana, your Microsoft CAB based product. The Silverlight equivalent would use Prism rather than CAB. Cabana was a pretty full featured application, not some simple demo and as such could be used as an application starting point which saved months and months of work.

 

What I would like to know is, if and when will you be releasing a DevForce Silverlight application built on Prism which will have the same level of functionality as Cabana?

I donít remember tweeting that I ďwas working on a Silverlight equivalent to CabanaĒ.  I can imagine myself saying that I intend to do such a thing. Iím not ready to start though.

 

When I wrote Cabana I had years of experience writing WinForms applications. I knew how folks tended to structure their UIs (the Outlook look) , how they did forms-over-data, how they presented modules in separate tabs of a shellís tab control.

 

I was also enamored of infrastructure that relied on inheritance.

 

Today, I donít know what the popular visual metaphors and interaction paradigms will be for Silverlight business applications. I think it is a misuse of Silverlightís potential to merely reproduce what was common for WinForms. I say that having done essentially that in Prism Explorer.

 

Today I realize that the deeply nested infrastructure that was Cabana (and CAB) is not such a great idea. Iím looking to thinner, more composed structures these days. If  you look at Prism and Prism Explorer you will see only shallow inheritance in the classes.

 

All in all, Iím a good six months from feeling ready to pronounce on what a Cabana equivalent should be. Then I can try to develop it. Better yet, Iím hoping to borrow from others.

 

If youíve been following my blog and my tweets youíll notice that I am much involved with the community of experts who are working through these patterns and paradigms.

 

Wish I had a better answer. I still feel that Silverlight productivity trumps WinForms productivity once you get the hang of it. Itís worth the journey.

To be honest I can't remember exactly what that tweet said so I paraphrased with wishful thinking in mind!

 

I too am enamoured with the relative simplicity (compared with CAB) of Prism and the overall productivity gains with Silverlight. I am thinking about delivering some small, simple apps first and keeping a close eye on the community for where thinking is going. I do not want to begin a large project only to flounder with concern over the best patterns.

 

I have built a fairly large application using Cabana as my base and DevForce Classic as it is now known. I can (and do) add new functionality with relative ease and I so greatly respect your work. The deep inheritance does however appear complex compared with how one might construct something similar with Prism.

 

I read your blog regularly and I am deeply impressed with DevForce Silverlight. I am on vacation now but if I'm honest I can't wait to get back to work on this stuff!

 

Thanks again Ward, keep up the great work.

Thanks for all of that encouragement, G Itís the kind of thing that keeps us motivated. Stay in touch Ė Regards, Ward
