Course description

In this training course, we will look at the background on mobile, what is happening in the marketplace, why cross platform development makes sense, and some general strategies for cross platform development with iOS, Android, and Windows. These platforms all have one thing in common; the platforms can all be targeted with the C# language. Next we will examine file linking, general abstraction, the observer pattern, partial classes, and conditional compilation. In file linking, we can use cross platform language features, such as calling web services, LINQ, XML, and JSON to handle the communication with a remote data source on both android and iPhone.


This course assumes that students have some programming background and experience using Visual Studio and Xcode. In addition, this course assumes knowledge of Visual C# and Mono for Android, as well as Objective C and Mono Touch. An understanding of XML is also required.
