Stephane/icustuds: Great post. Feel free to post questions on my blog on MSN Spaces if you see a relevant thread there. I am glad you could relate to the philosophy of this platform for your work on Smart Clients / Applications. It is fair to compare with what is on the market out there today although Avalon was planned for a long long time and apart from Sparkle, things were public for at least 2 years (you could use XAML/Avalon betas, etc).
Actually I was not making any reference to value or anteriority in my comparison, forgive me if it looked like I did. I just discovered the concept of RIA through Macromedia's beta related to Flex during past year and a half, but discovered Avalon only 2
or 3 months ago (even if it apparently was around for much longer) but did not give lot of attention since I’m looking for a designer approach of RIA (GUI) which was provided by Flex Builder. The announcement of Sparkle changed the game and gathered my attention
to Avalon for a better look. My comparison was just a way to make sure I’m making the right relation between the tools I’m using from Macromedia, and the tools I could be using instead from Microsoft (some of Sparkle features such the timeline and the ultra
simplified way to manipulate 3D would make me do the switch).
I will post more tech specific questions to your MSN Space.
