1. Starting developing with XAMARIN
and
why you should start learning it
right now
Oleksandr Proskura Xamarin developer, Trinetix

2. Part I. Xamarin for all

3. Xamarin ecosystem
Build Test Distribute Learn

4. Build – Visual Studio

5. Test - Xamarin test cloud

6. Distribute - HockeyApp

7. Learn – Xamarin University

8. Part II. Xamarin for developers

9. Xamarin supported OS

10. Xamarin Games & Graphics
• MonoGame
• CocosSharp
• Urho 2D/3D
• SkiaSharp 2D

11. Xamarin ways
Xamarin.Forms Xamarin native
Xamarin

12. Xamarin native

13. Xamarin.Forms

14. Xamarin.Forms and PCL

15. Xamarin.Forms vs Xamarin native

16. Both –
Xamarin.Forms and Xamarin native
create native application
for each target OS.
Really?

17. How does it work?
C#
Native
SDKs
Native app
(.apk/.ipa)
Xamarin magic?

18. Xamarin.iOS
C# AOT .ipa

19. AOT compilation

20. Xamarin.iOS Architecture

21. Access to native SDKs from C# (bindings)

22. Xamarin.Android
C#
IL
+ MonoVM
+ JIT
.apk
*Xamarin provides experimental AOT+LLVM for Android

23. Xamarin.Android Architecture

24. MVVM – best pattern for Xamarin

25. High flexibility
ModelView
Looks fine :) Lives its own life
?
ViewModel
I can do everything!

26. Xamarin.iOS limitations
•Limited Generics Support
•No Dynamic Code Generation
•Reflection.Emit
•COM bindings
•The JIT engine

27. Xamarin.Android limitations
• Limited Dynamic Language
Support
• Partial Java Generics Support

28. Xamarin benefits
• C# - one language – all platforms
• VS – best IDE ever
• Code sharing
• Xamarin ecosystem supports full
app lifecycle
• Performance Close to Native
• Native User Experiences
• Full Hardware Support

29. Xamarin cons
• Slightly Delayed Support for the
Latest Platform Updates
• Small Xamarin community
• Development limitations

30. Try Xamarin if you:
• Know C#
• Want to be mobile dev for both
platforms
• Android/iOS dev and want to try
another one OS

31. Thanks for watching!
Any questions?
