4. What does an enterprise team need? Lots of Skills Needed – Multiple languages – Multiple Platforms – Multiple Devices – Different Implementation processes

5. Development Options Mobile Web Sites HTML5 Hybrid Apps PhoneGap Cordova Native Apps Java Objective-C Swift.NET Xamarin Content Delivery Quick to develop Content Delivery Quick to develop Cross Platform Quick to develop Cross Platform Quick to develop Best Experience More $, More Time Best Experience More $, More Time

6. Why Xamarin? Leverage C#/.NET DevelopersBuild Cross Platform Native AppsReuse code across platformsAccess to Native controls and APIsNative Performance

7. Write Once, Run Everywhere Portable Class Libraries Shared Projects Xamarin.Forms

8. Cost Traditional iOS & Android Mac Mobile Devices Total Cost: ~ $3,000 Xamarin iOS & Android Mac Mobile Devices Xamarin Platform – iOS $900 – Android $900 Total Cost: ~ $4,800 + $1,800

10. Consumer Based Apps Brand will matter Complete control over layout and design by platform Depending on the specific design might need to create custom UI for each platform

11. Internal Apps Xamarin.Forms for quick development Deliver for BYOD situations Tablet and/or Phones Shared codebase – Communications tools and data access tools

12. Xamarin Toolset Xamarin Studio – Mac Visual Studio Projects Build Server for iOS builds from Visual Studio

13. Cross Platform Project Structure Visual Studio Solution - Mobile Models Project Shared App Logic iOS Project Shared UI Project Android Project Windows Mobile Project

14. Code Examples Hello World App

15. Code Examples Xamarin.Forms

16. Data Access Enterprise Framework – WebAPI, Restful services – Breeze Local Storage – Key/Value pairs – Files Text Files Binary Data Serialized Files – Database (SQLite)

17. Code Examples Data Access Local Storage

18. Xamarin Benefits Leverage current.NET team Faster time to market for mobile apps Shared code across devices Target more devices Quickly deploy internal Line of Business Apps

19. Orchestrate Demo Real World Xamarin App Native code Sync with WebAPI, Breeze SQLLite for Offline usage
