Xamarin is a cross-platform development tool that enables the creation of native apps for Android, iOS, and Windows using a single shared .NET code base in C#. It provides tools like Xamarin.Forms for user interface design and integrates with Visual Studio for development and testing. Additionally, Visual Studio App Center supports continuous integration and app analytics, enhancing the development process.

1. Xamarin

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.

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
