Course description

Applications live on data. These applications can vary from an online social network service, to a company’s internal database, to simple data, and all points in between. This Course will focus on how to easily access data on the device, communicate back and forth with a web service, and then finally to a SQL server database.

Prerequisites

This course assumes that students have some programming background and experience using Visual Studio 2013. In addition, the course assumes knowledge of Visual C#, Xamarin.iOS, and Xamarin.Android in the Windows and MAC environment. An understanding of XML is also required. It would be helpful to have viewed these other LearnNowOnline courses; Xamarin Tool with Various Mobile Platforms, Xamarin Mobile and Web Services, Xamarin Cross Platform and File Linking, and Xamarin Cross Platform: PCL and Razor before viewing this course.
