I've been reading up on some Microsoft tutorials getting ready to start teaching myself WPF programming, having been a longtime Windows Forms and Webforms programmer and trainer. The way I understand it, WPF interfaces are basically created by producing underlying xaml, that can be produced by a designer using Microsoft Expression products. My question is geared toward other professional .net developers who either themselves, or through their company, use the services of professional designers. If you or your company already have a relationship with a good designer, and that designer's experience is primarily with adobe tools such as dreamweaver, illustrator, and photoshop - can they still use their own tools to create WPF-compatible xaml that will work with Visual Studio? Or do they have to learn Expression tools instead? Does anyone know of an upcoming Dreamweaver plugin, or one that already exists that allows this?
