Used by more than 20% of Fortune 500 companies

Reuse your company’s current development investmentKeep using Visual Studio (or Xamarin Studio)Same-day support for all new API’s 100% platform API coverageAll latest C# goodness – LINQ, async\await, TPLAverage of 75% code sharing!Scan your code for conformance: scan.xamarin.com

Why Xamarin?

Xamarin Application Architecture

PhoneGap

PhoneGap is an open source mobile development framework

Developed by Nitobi SoftwarePurchased by Adobe

Renamed to Cordova after the shift to Adobe

Enables building mobile device applications

using the Web technology stack –HTML, CSS, and JavaScript

Hybrid Apps

A PhoneGap application is considered hybrid

They are neither truly native, nor purely web-basedAll layout rendering is done via the Web View

Supports 7 platforms

What Is PhoneGap All About?

WrapperBridge

Getting Started with PhoneGap

Set up your development environmentPC, MacXcode, Eclipse, Visual StudioSDKs, JDKs, plug-insSame as for Native Development

Adobe® PhoneGap™ Build – upload your HTML5, CSS, and JavaScript assets to a cloud service which does the work of compiling for you
