In my expirience the the mix of XML and code quickly grows into a worse situation It depends on how you do it. In any environment, there are ways that scale and ways that don't. We've had very good results (seperation of concerns, plugability, extensiblity, blendability) using the ViewModel pattern, an IOC Container and Command objects. The good part of WPF is that you can do all this, or other things, if you want. The same is not true of Windows forms. WPF enables some nifty ways to scale that are just not there in Windows forms.
