Most business and consumer mobile apps connects to a backend to store data. As a developer, you need to understand how to implement such a system. HTTP Requests, REST API, JSON, CRUD, DataBinding and HTTPClient are the technology concepts used for the communication between a mobile application and a web service. This course explains these technologies in a simple way by showing their practical side. The objective is that the learner will be able to build his first native cross platform mobile app (iOS & Android) that communicates with a backend, in less than half a day!

As a good preparation for professional development, this course uses the same tools used by professional developers: Visual Studio, Postman, ASP.NET Core, Xamarin Forms and Azure App Service.
