Automatically test your app on!hundreds of mobile devices !

Create native iOS, Android, Mac and Windows apps in Visual Studio and C#

What is native?!

The Anatomy of a Native App!

Xamarin apps look and feel native because they are native!

Native User Interfaces! Native API Access! Native Performance!

Architecting !Mobile Apps!

The Silo Approach!

Build App !Multiple Times!

The Write-Once-Run-Anywhere Approach!

Lowest Common!Denominator!

Xamarin’s Unique Approach!

Native With !Code Sharing!

How does it work?!

Windows APIs!

iOS APIs | 100% Coverage!

Android APIs | 100% Coverage!

Anything you can do in Objective-C or Java !can be done in C# with Xamarin using Visual Studio!

Xamarin.iOS does full Ahead Of Time (﴾AOT)﴿ compilation to produce an ARM binary for Apple’s App Store.

Native Performance

Xamarin.Android takes advantage of Just In Time (﴾JIT)﴿ compilation on the Android device.

Always Up to Date

Same day support for iOS 5, iOS 6, iOS 6.1, iOS 7, iOS 7.1!

Emerging Technologies & Devices Always up-‐to-‐date with the latest APIs from

Apple and Google.

Android Wear Google Glass Amazon Fire Phone Amazon Fire TV!
