#Career Guideline

Silo Approach

Build Apps Multiple Times

• Multiple Teams

• Multiple Code Bases

• Different toolsets

HTML - Write Once, Run Anywhere Approach

• Lowest common denominator

• Browser fragmentation

• Developing & designing for 1 platform, happen to get other platforms

Start with HTML5/CSS3/JavaScript Use PhoneGap Deploy to platforms

What is Xamarin?

Xamarin’s Unique Approach

• Native User Interface

• Native Performance

• Shared code across platforms

• C# & .NET Framework

• Full API Coverage

With Xamarin.Forms:

more code-sharing, native controlsTraditional Xamarin approach

Layouts

Entry Image Label ListView Map

OpenGLView Picker ProgressBar SearchBar Slider

Stepper TableView TimePicker WebView EntryCell

ImageCell SwitchCell TextCell ViewCell

Controls

Use a single API to generate native, platform-specific user

interfaces

At runtime, each Xamarin.Forms page and its

controls are mapped to platform-specific

native user interface elements

Xamarin.Forms Example

Native API access

.NET + Windows APIs

.NET + iOS APIs | 100% Coverage

.NET Android APIs | 100% Coverage

Native Performance

Xamarin.iOS does full Ahead Of Time

(AOT) compilation to produce an

ARM binary for Apple’s App Store.

Native Performance

Xamarin.Android takes advantage

of Just In Time (JIT) compilation on

the Android device.

Any Other Reason???

Anything you can do in Objective-C, Swift, or Java

can be done in C# with Xamarin using Visual Studio

Real-time monitoring. Track crashes

and exceptions to understand what

is happening with live users.
