XamChat – a Cross-platform App

by Jonathan Peppers | February 2014 | Open Source

This article is written by Jonathan Peppers, the author of Xamarin Cross-platform Application Development. Xamarin technologies are used to develop real-world applications for iOS and Android.

This gives new developers a project where they can focus on the concepts they are trying to learn without the overhead of fixing bugs or following customer requirements. To increase our understanding of Xamarin Studio and cross-platform development, let's develop a simple app called XamChat for iOS and Android.
