The document discusses developing cross-platform mobile applications using Xamarin. It introduces Xamarin, which allows developers to build native iOS and Android apps using C# and .NET. It highlights that Xamarin apps look and feel native while sharing code across platforms. The document also covers architecting mobile apps with Xamarin, using Xamarin.Forms to build user interfaces with shared code, and includes a demo section.

- 2. Agenda • Why Native? • What is Xamarin? • Architecting Mobile Apps • Xamarin Forms • Demo
- 3. Why Native?
- 4. Two Challenges for Building Apps
- 5. The Anatomy of a Native App Xamarin apps look and feel native because they are native Native User Interfaces Native API Access Native Performance
- 6. Cross-Platform Mobile Development • Building high-quality Apps is hard: • Different presentation styles, interaction styles and software stacks • Devices have different screen sizes, input modes and hardware capabilities • New devices and OS versions are introduced multiple times per year • Network connectivity and power levels fluctuate widely in typical usage scenarios • New consumer applications regularly extend and revise the standards and set the bar higher for good mobile applications
- 7. 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.
- 9. Xamarin brings open source .NET to mobile development, enabling every developer to build truly native apps for any device in C# and F#. What is Xamarin?
- 10. What is Xamarin?
- 11. Xamarin Nat Friedman Miguel de Icaza James Montemagno CEO and Co-Founder CTO and Co-Founder Developer Evangelist
- 12. Make it fast, easy and fun to create great mobile apps Xamarin’s Mission
- 14. Explosive Growth 350+ employees 15,000+customers Customers in 120 countries 1,400,000+ registered developers 32,000 new developers per month Visionary in the Gartner Magic Quadrant# of developers
- 15. Explosive Growth
- 17. Build App Multiple Times • Expensive to staff multiple platform- specific teams • Expensive to maintain multiple code bases • Slows innovation
- 18. The Write-Once-Run-Anywhere Approach • Non-standart UI • Limited API access • Non-native performance • Poor user experience
- 19. Xamarin’s Unique Approach Native With Code Sharing
- 20. Windows APIs
- 21. iOS APIs | 100% Coverage
- 22. Android APIs | 100% Coverage
- 23. Xamarin Designer for iOS in Xamarin Studio
- 24. Anything you can do in Objective-C or Java can be done in C# with Xamarin using Visual Studio
- 25. Xamarin Forms
- 28. Xamarin.Forms Quickly and easily build native user interfaces using shared code Xamarin.Forms elements map to native controls and behaviors Mix-and-match Xamarin.Forms with native APIs Shared App Logic Shared UI Code
