Mike Swanson wanted to use XAML and the new Avalon, but was having trouble getting his Adobe Illustrator files ported over so he wrote his own converter. This thing is awesome for graphic designers who want to work with developers on UI's! Anyway, he's releasing it as a free download (he wrote this on nights and weekends). The current version works with Adobe Illustrator CS and CS2 running on Windows. Note that this plug-in is not endorsed, warranted, or supported by Microsoft. The original news on Channel 9.
