If you’ve been reading about all the new features in Flash Builder 4, but are still working in Flex Builder 3 because you’re working on an existing project, then you might want to check out the article I’ve written for the Adobe Developer Centre.
The article explains how you can benefit from most of the new features in Flash Builder 4 whilst working on existing Flex 3 projects (and you don’t have to migrate the application to use the Flex 4 SDK if you don’t want to).
In the article I cover the following scenarios:
- I want the new Flash Builder 4 features, but can’t switch SDK versions
- I want the new Flash Builder 4 features and the faster Flex 4 compiler, but I need to maintain my application’s existing behaviour
- I want the new Flash Builder 4 features and all the new Flex 4 language features, but don’t want to adopt the new Spark component architecture
- I want the new Flash Builder 4 features, all the new Flex 4 language features and I want to add the Spark-based components to my existing application
Moving your Flex 3 project into Flash Builder 4 can be as simple as just importing it, optionally you can choose to undertake some migration to use Flex 4 SDK features if you have the time for your current project.
Remember that you can use the Adobe Forums for Flex 4 and Flash Builder 4 should you have any questions about moving or migrating your application.
