title: wpf and prism: where is link between view and viewmodel
body: <p>I've inherited a WPF Prism application and I'm having a tough time seeing how viewmodels are linked to their respective views (xaml). Sometimes the view's code behind sets the DataContext to the proper viewmodel but the application I'm working on does not have this being set in the code behind. Where else can this be set in a Prism application?</p>
