In this chapter, we created a live API from scratch using Azure App Services. We then created a data service within our app to handle communication between the app and the API. Then, by adding a reference to this service to our ViewModels, we quickly transformed the app from using static data to using live data from our new API. Finally, we set up offline data caching. In the next chapter, we will add authentication to our API and update the app with sign in capabilities.
