Cross Platform Mobile Dev with C# and Xamarin (CapArea.NET User Group 5/27/14)
This document discusses cross-platform mobile development using C# and Xamarin. It introduces Xamarin, which allows developers to build native iOS and Android apps using C# instead of Objective-C and Java. This enables sharing up to 90% of code across platforms. Xamarin uses the MVVM pattern to separate UI, business logic, and data. Shared portable class libraries contain core app code, while platform-specific projects contain UI code. This approach allows building each app's UI natively while sharing a common codebase, reducing development and maintenance costs compared to building each app separately.

- 4. THE PROBLEM WITH TRADITIONALNATIVE MOBILE APP DEV… Native mobile apps are great but here’s the problem: Several Platforms: Windows, iOS, Android Several Languages: C#, Objective-C, Java Maintenance nightmares Customers and end-users suffer
- 5. THE BENEFITS OFMULTI- PLATFORM NATIVE MOBILE APP DEV WITH C# Develop for all platforms with a single language – C# - using Xamarin Harness the power of the .NET framework Single solution with shared code Unified and consistent maintenance/testing Feature parity across platforms = happy end users + C#
- 6. WHAT IS XAMARIN? Xamarinis built on Mono Allows native app compilation on Android and iOS using C# 100% API Coverage – All iOS and Android APIs are exposed as C# class libraries Up-to-date with API releases from Apple and Google
