In this chapter, we successfully created an app for three different operating systems – iOS, Android, and Windows – and three different form factors – phones, tablets, and desktop computers. To create a good user experience on all platforms and form factors, we used FlexLayout and VisualStateManager. We also learned how to handle to use different views for different form factors, as well as how to use Behaviors.
The next app we will build will be a chat app with real-time communication. In the next chapter, we will take a look at how we can use the SignalR service in Azure as the backend for the chat app.
