Course description

In this course we’ll cover cross platform mobile development using Xamarin. First we’ll cover Portable class libraries (PCLs). PCLs are tools provide .NET developers a way to share code between platforms with one library. PCLs help developers reduce the time and costs of development and testing code. With a PCL project, one library can be used by multiple platforms. Then we’ll move onto Mobile web apps. Mobile web apps are a very popular mechanism to target mobile devices. Unfortunately, there are times that a mobile web app cannot access device specific features. Xamarin provides a mechanism to host an ASP.NET MVC Razor Web Template/Page within a native application. This provides the cross platform capabilities of the web while still allowing applications to access native features of device.


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, and Xamarin Cross Platform and File Linking, before viewing this course.
