I’ve just got my Flash Builder 4 and now I want to create a project. The Flash Builder 4 IDE shows me 2 options: (1) Flex Project, (2) Flash Professional Project.
I know that “Flex Builder” was the former name of “Flash Builder”, however, I don’t know which of the 2 project types mentioned above is more advanced.
Read this documentation about creating projects in Flash Builder. Read this documentation on the Flash Professional project type.
You’re formal question was “which of the 2 project types mentioned above is more advanced.” and I’m not sure how to answer that. They are different, and used for different purposes. I might compare them to a stapler and tape. Both can attach two pieces of paper together, but I wouldn’t consider one more advanced than the other. They are just different.
