Is there an actionscript extension for visual studio?

Question

I prefer the VS IDE over flex builder.

Answer 1

There used to be a few alternative commercial VS plugins for Flex dev but they have all disappeared. IntelliJ IDEA and the official (mostly unsupported) Adobe Flex IDE are the only commercial remaining offerings.

As suggested there is the free and opensource FlashDevelop IDE which is inspired by Visual Studio:
