According to Joe Stegman WPF/E is not a “me too” technology that follows in the path of Flash and other rich media technologies. While there are many aspects of this proposed technology that would appear to indicate it is following this road, the biggest distinction is that it is designed with Microsoft developers in mind. This means (hopefully) a reduction in the use of Javascript and an increase in the amount of managed code we have to write for a rich web experience. I must admit at this point I can’t wait to see the CTPs as I think that the “proof is in the pudding”.
