3. What is Xamarin? Xamarin is a Microsoft-Owned,
One Million Developers use Xamarin Products in more than 120 countries around the world.
Xamarin is a cross-platform development tool. It solves dilemmas many developers face when developing cross-platform apps: separate coding languages and UI paradigms. With Xamarin, you can use C# for iOS, Android, and Universal Windows apps.

4. Why Xamarin?
Xamarin enables developers to reach all major mobile platforms!
Deliver native Android, iOS, and Windows apps, using existing skills, teams, and code.
Native User Interface, Native Performance
Native API Access (100%)
Shared Code Across Platforms
Note: our core WMS team learn and Build this code in C#.net, for UK we build Hybrid app with help of Jquery, CSS, JS, HTML5…

5. Shared Code Across Plateform
Note: same code can run for all three platforms iOS, Windows

6. Mobile App Development Approaches
Let’s talk about the state of mobile development today

7. Drawbacks of coding in Native …
Build Apps Multiple Times
Multiple Teams
Multiple Code Bases
Different toolsets
Multiple Teams
Multiple Code Bases
Expensive & Slow
Positive = Great apps delivered to user’s platform
Negative = Development hampered by multiple code bases & fragmentation

8. Xamarin’s Unique Approach
Native User Interface
Native Performance
Shared code across platforms
C# & .NET Framework
Full API Coverage
UI build natively per platform, leveraging C#
C# + XAML
C# + XML
C# + XIB
One shared app logic code base, iOS, Android, Mac, Windows Phone, Windows Store, Windows

9. Mobile Plateform Stack UK App –Hybrid, LC App- Xamarin

10. Xamarin Native App VS Hybrid HTML App
Let’s talk about the state of mobile development today

11. Making the Right Choice for the Enterprise
Xamarin Native APP
Hybrid HTML App
True Native Compilation using JIT, AOT compilers (ahead of time)
Not Real Native compilation as it uses Cordova Wrapper
Works with the Latest SDK
Need to wait for the new API to integrate
Native UI Look as well as Behave
Mimic Native UI
No Browser comptability required
Browser related issue persist as it uses Web View.
Let’s talk a bit about C# and why it is awesome.

12. 25 % Faster
Cross Plateform Native apps started faster than the Hybrid HTML version
Let’s talk a bit about C# and why it is awesome.

13. Cross Plateform Native apps loaded large datasets faster than Hybrid HTML app
Let’s talk a bit about C# and why it is awesome.

14. -50 % Less
Cross Plateform Native apps uses less memory than Hybrid HTML app
Let’s talk a bit about C# and why it is awesome.

15. -76 % Less
Cross Plateform Native apps uses less CPU time than Hybrid HTML app
Let’s talk a bit about C# and why it is awesome.
