Cross-platform mobile development using Xamarin and C#


Published on

Recent increase in demand of the cross-platform mobile development born a few great technologies. Some of them are good, others are not, but just few of them provides native platform experience. Hybrid applications work great in this case. Taking into account responsive design makes it even better. However, users do not need “just functionality” and responsive layout any more. They need, even demand great user experience, which should be attractive, convenient, powerful, responsive and unique. During this session, I want to tell you how Xamarin and Mono help to deliver native experience for iOS, Android, Windows Phone platforms having most of your code reused between platforms and written in C#.

This session will give you an overview of cross-platform development basics for iOS, Android and Windows Phone platforms using Xamarin, .NET and C#
You will know:
- Xamarin concept. MonoTouch & MonoDroid
- Developing under Windows & Mac. Environment requirements.
- Visual Studio vs Xamarin Studio
- MvvmCross libraries
- Utilization of Portable Class Libraries & Project Links for better code sharing
