Download the Expression Interactive Designer for free and to easily view and modify the xaml.
This plug-in allows designers to create compelling 3D user interfaces in Maya and export to XAML, the next generation application GUI markup language for windows and the web. Objects created in Maya can be used as hit targets, windows forms controls, and more. Because the objects are kept as vector data in the interface, the user can scale the entire application and keep the same look and feel. Look for future export features like animation, mesh optimization, xml formatting, and the ability to specify the WPF target type template for Maya objects.
