While at Flash on the Beach this year I gave a one-day workshop on getting up to speed with Flex 4 if you are coming from a pure ActionScript background. Below are the slides from that workshop as well as a copy of the FXP file that contains all of the examples / samples. I’ll be doing some screencasts around some of the techniques and processes in the coming weeks so don’t worry if you attended and it’s started to fade away; or if you didn’t manage to come along and want to know more.
You can download the associated FXP here.
