  1. Introduction to Xamarin C# Everywhere • Mike Bluestein Developer Evangelist Xamarin mikeb@xamarin.com @mikebluestein

  2. What is Xamarin? • Xamarin enables developers to reach all major mobile platforms! • Native User Interface • Native Performance • Shared Code Across Platforms • C# & .NET Framework

  3. Mobile Development Approaches

  4. Silo’d Approach Build Apps Multiple Times • Multiple Teams • Multiple Code Bases • Different toolsets

  5. Write Once, Run Anywhere Approach • Least common denominator • Browser fragmentation • Developing & designing for 1 platform, happen to get other platforms Black Box

  6. Xamarin’s Unique Approach • Native User Interface • Native Performance • Shared code across platforms • C# & .NET Framework • Full API Coverage

  7. Hybrid Apps - Portable Razor

  8. Why C#?

  9. C# Is Awesome LINQ Support Work With XML Easily XDocument Event Handling & Delegates

  10. C# Is Awesome – JSON Made Easy Json.NET offers simple conversions to and from JSON strings and .NET objects, with SerializeObjectand DeserializeObject methods.

  13. Async/Await Write Beautiful & Maintainable Code

  14. Why Xamarin?

  15. Write Everything in C# iOS, Android, Windows, Windows Phone, Mac 2.5+ Billion Devices!

  16. Xamarin HistoryOver a Decade of Enterprise Production Use 500,000+ Developers 100+ Partners 100+ Components Reach 200,000 Developer Mark 2013 2011 2012 2009 2003 2001 2000 XimianFounded Mono Started XimianAcquired by Novell First iOS product (now Xamarin.iOS) launches Xamarin Founded First Release of Xamarin.Android First release of Xamarin.Mac LaunchPartnerProgram Xamarin 2.0 Component Store Evolve 2013 Xamarin Test Cloud Microsoft Partnership

  17. 100% API Coverage Anything you can do in Objective-C or Java can be done in C# and Visual Studio with Xamarin!

  18. Native Performance Xamarin.iOS does full Ahead Of Time (AOT) compilation to produce an ARM binary for Apple’s App Store. Xamarin.Android takes advantage of Just In Time (JIT) compilation on the Android device.

  19. Always Up to Date Always up-to-date with the latest APIs. Great track record. Shipped same-day support for iOS 5, iOS 6, iOS 6.1, iOS 7 .

  20. Code Sharing: Accelerate Development • Up to 90% Code Reuse • Leverage existing libraries • NuGet Support Code-sharing stats from iCircuit, built with Xamarin and featured on the App Store. Source: http://praeclarum.org/post/42378027611/icircuit-code-reuse-part-cinq

  21. Portable Class Libraries • 1 Assembly • Multiple Platforms • Including: • Xamarin.Android • Xamarin.iOS

  22. Portable Class Libraries Features • Centralized Code Sharing • How you expect it to work • Debug seamlessly into and out of PCL • Project/Assembly Sharing • NuGet

  23. PCLs – Well Documented

  24. Microsoft and Xamarin Partner Globally With Xamarin, developers combine all of the productivity benefits of C#, Visual Studio 2013 and Windows Azure with the flexibility to quickly build for multiple device targets.” S. Somasegar, Corporate Vice President, Microsoft
