Xamarin

Xamarin is an open-source platform for building modern and performant applications for iOS, Android, and Windows with

Definition of Xamarin

It’s impossible to ignore Xamarin when talking about the key approaches to mobile application development. Xamarin is a tool used for cross-platform mobile app development that allows engineers to share about 90 percent of code across major platforms. Being a comparatively new tool, it is based on the Microsoft technology stack and already has a community of over 1.4 million developers. Xamarin uses a single language, C#, to create apps for all mobile platforms. Unlike interpreted solutions, such as Appcelerator Titanium, Xamarin is natively compiled, which makes it a go-to option for building high-performance apps with native look and feel.

Added features

Xamarin contains bindings for nearly the entire underlying platform SDKs in both iOS and Android. Additionally, these bindings are strongly-typed, which means that they’re easy to navigate and use, and provide robust compile-time type checking and during development. Strongly-typed bindings lead to fewer runtime errors and higher-quality applications.

Xamarin provides facilities for directly invoking Objective-C, Java, C, and C++ libraries, giving you the power to use a wide array of third party code. This functionality lets you use existing iOS and Android libraries written in Objective-C, Java, or C/C++. Additionally, Xamarin offers binding projects that allow you to bind native Objective-C and Java libraries using a declarative syntax.

Xamarin applications are written in C#, a modern language that includes significant improvements over Objective-C and Java such as dynamic language features, functional constructs such as lambdas, LINQ, parallel programming, generics, and more.

Xamarin applications use the .NET BCL, a large collection of classes that have comprehensive and streamlined features such as powerful XML, Database, Serialization, IO, String, and Networking support, and more. Existing C# code can be compiled for use in an app, which provides access to thousands of libraries that add functionality beyond the BCL.

Xamarin uses Visual Studio, a modern IDE that includes features such as code auto completion, a sophisticated project and solution management system, a comprehensive project template library, integrated source control, and more.

Xamarin offers sophisticated cross-platform support for the three major platforms of iOS, Android, and Windows. Applications can be written to share up to 90% of their code, and Xamarin.Essentials offers a unified API to access common resources across all three platforms. Shared code can significantly reduce both development costs and time to market for mobile developers.
