First part in the Microsoft webcast series i presented: Cross platform mobile development using Xamarin. The first webcast will focus on the challenges on developing for multiple mobile platforms and how Xamarin enables developers to do this quicker and more efficiently. In the second part of the webcast we will look at how this development is done using Visual Studio or Xamarin Studio.

4. Series Part 1: Introduction to Xamarin mobile development Today Part 2: Building Cross Platform Mobile Applications using Xamarin September 28, 2016 – 11:00-12:00 CET Part 3: Mobile Dev Ops powered by Xamarin and Microsoft October 12, 2016 – 11:00-12:00 CET
5. • Approaches to Mobile Development • Introduction into Xamarin • Demo: Xamarin in action Agenda
7. Approaches to mobile Development
8. SILO Approach iOS Windows Android Swift /Objective- C Xcode C# Visual Studio Java Android Studio No shared code • Many languages & development environments • Multiple teams
9. WRITE once, run everywhere approach App Generator Lua Javascript Actionscript HTML+CSS Limited native API access • Slow performance • Poor user experience
11. Shared C# codebase • 100% native API access • High performance iOS C# UI Windows C# UI Android C# UI Shared C# Mobile The Xamarin approach
12. Xamarin + Xamarin Forms Traditional Xamarin Approach With Xamarin.Forms: More code-sharing, all native iOS C# UI Windows C# UI Android C# UI Shared C# Backend Shared UI Code Shared C# Backend
13. Taking it even a step further Shared C# codebase • 100% native API access • High performance iOS C# UI Windows C# UI Android C# UI Shared C# Mobile C# Server Linux/Mono CoreCLR Azure Shared C# Client/Server
14. 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.
15. Anything you can do in Objective-C, Swift, or Java can be done in C# and Visual Studio with Xamarin.
18. LINQ Support Work with XML Easily Event Handling & Delegates
19. Json.NET offers simple conversations to/from JSON strings and .NET objects:
21. Microsoft.Phone Microsoft.Networking Windows.Storage Windows.Foundation Microsoft.Devices System.Data System.Windows System.Numerics System.Core System.ServiceModel System.Net System System.IO System.Linq System.Xml C#
22. MapKit UIKit iBeacon CoreGraphics CoreMotion System.Data System.Windows System.Numerics System.Core System.ServiceModel System.Net System System.IO System.Linq System.Xml C# iOS – 100% API Coverage
23. Text-to-speech ActionBar Printing Framework Renderscript NFC System.Data System.Windows System.Numerics System.Core System.ServiceModel System.Net System System.IO System.Linq System.Xml C# Android – 100% API Coverage
24. TOOLS
25. VISUAL STUDIO INTEGRATION
26. XAMARIN STUDIO
27. Windows / VS OSX / XS Supported Supported Supported * Supported Supported Not supported * Requires connection with OSX build host VISUAL STUDIO INTEGRATION
28. Additional required tooling JAVA JDK + Android SDK XCODE / iOS SDK Windows UWP SDK
29. Sharing code
30. 1 Assembly Multiple Platforms PORTABLE CLASS LIBRARIES
31. SHARED LIBRARIES
32. NUGET
33. COMPONENTS
35. DEMO APP: XAMLOC NATIVE IOS,ANDROID AND WINDOWS XAMARIN APP App that uses GPS to find out in which country the users is and allows the user to upload country + username to the backend so we can get an overview where our webcast viewers are from.
