MvvmNavigationToolkit

Navigation toolkit for Windows Phone & Windows Store apps

It's all about wiring VM together with Views using fluent syntax:

        _navigationBuilder
            .RegisterViewModel<FrameViewModel>().StaticResource().WithoutView()
            .RegisterViewModel<MainViewModel>().Singleton().ForView<MainPage>()
            .RegisterViewModel<NotesViewModel>().StaticResource().ForView<NotesView>()
            .RegisterViewModel<NoteViewModel>().ForView<NoteView>()
            .RegisterViewModel<AppSettingsViewModel>().ForView<AppSettingsView>()
            ;

And now in any ViewModel you can open one in this way:

    ServiceLocator.Resolve<NotesViewModel>().Show();
