More good news on the conversion front:
I'm very happy to announce that there's a new SWF to XAML conversion tool in town, and although I haven't had a chance to play with it myself (no demo version is available), it sounds promising. Specifically—and unlike my SWF2XAML utility—it also appears to convert both animation and sound. Check out the demo page for some nice SWF and XAML comparisons. I have to add that the user interface looks quite unique! The $249 USD purchase price gets you the application and a year of free upgrades.
