An overview of Xamarin. The intention of this presentation is to provide basic understanding about Xamarin.

1. Xamarin
Deliver native Android, iOS, and Windows apps with a single shared .NET code base.
Jacob Nelson
Software Architect

2. Xamarin?
Xamarin is a cross-platform development tool. With Xamarin, you can
use C# for iOS, Android, and Universal Windows apps.
With Xamarin Forms, User Interface design for all three platforms can
be accomplished within its XAML-based framework.

5. User Interface
Xamarin.Android IDE
• Xamarin.Android Designer (visually create a user interface.)
• programmatic user interface creation in code
Visual Studio
Xamarin.iOS IDE
• iOS Designer
• Xcode's Interface Builder
• programmatic user interface creation in code
• Visual Studio for Mac or Xcode
Xamarin.Forms IDE
• XAML (user interface is defined in an XML file using the XAML syntax) Visual Studio for Mac or Visual Studio

6. Xamarin.Android
Xamarin.Android exposes the complete Android SDK for .NET
developers. This helps to build fully native Android apps using C# using
Visual Studio IDE.

7. Xamarin.iOS
Xamarin.iOS exposes the complete iOS SDK for .NET developers. This
helps to build fully native iOS apps using C# using Visual Studio.

8. Xamarin.Forms
Xamarin.Forms is a cross-platform UI toolkit that allows developers to
efficiently create native user interface layouts that can be shared across
iOS, Android, and Universal Windows Platform apps.

9. Visual Studio App Center
• Automatically build your app, test it on real devices, and distribute it
to beta testers
• Collect crash reports and user analytics, including custom events.
• Testing application in a hosted device lab with 1000s of real iOS and
Android devices.
• Receive test results, full-resolution screenshots of every step, along
with performance metrics.

10. Continuous Integration
• Using App Center with Xamarin
(Build solutions with App Center, straight from GitHub, VSTS, or Bitbucket. )
• Using TeamCity with Xamarin
• Using Jenkins with Xamarin
