I am pleased to announce that we have made the LCDS 3 beta available (require Flash Builder 4 Beta) for preview. There is a lot of new and interesting features, including the ability to develop flex applications from a model. We have provided seamless developer, deployment experience that should definitely improve developer’s productivity.
You can find more information on labs.adobe.com.
We have a couple of introductory videos that should help you get started. Some of the folks are putting together more videos that walks through specific features in more detail, but those will not be available until the end of this week or early next week.
