In my sessions in Tech Ed India this year where I presented on Avalon, the most asked question how do I generate XAML file instead of hand-coding them. The answer I gave was that Adobe is likely to release an Official Plug-In that will export to XAML around Avalon launch-time. It turns out that there is a free plug-in now available (in beta) from a Microsoft Engineer Mike Swanson. Click here to download it.
