Cross-Platform User Interfaces with Xamarin.Forms

Xamarin.Forms is a cross-platform natively backed UI toolkit abstraction that allows developers to easily create user interfaces that can be shared across Android, iOS, and Windows Phone. The user interfaces are rendered using the native controls of the target platform, allowing Xamarin.Forms applications to retain the appropriate look and feel for each platform.

Section Overview

The documents in this section discuss cross-platform application development using Xamarin.Forms.

Introduction To Xamarin.Forms

This document discusses what Xamarin.Forms is and some of the key concepts for developing applications, including view and layouts, the ListView control, data binding and navigation.

Xamarin.Forms Controls Reference

This document is a quick reference to the UI views that make up the Xamarin.Forms framework, such as Pages, Layouts, Views and Cells.

Working with different aspects of the Xamarin.Forms APIs including images, fonts and files.

Customizing Controls for Each Platform

Custom Renders let developers 'override' the default rendering of Xamarin.Forms controls to customize their appearance and behavior on each platform (using native SDKs if desired).

Accessing Native Features via the DependencyService

The DependencyService provides a simple locator so that you can code to Interfaces in your shared code and provide platform-specific implementations that are automatically resolved, making it easy to reference platform-specific functionality in Xamarin.Forms.

Publish and Subscribe with MessagingCenter

Xamarin.Forms MessagingCenter enables view models and other components to communicate with without having to know anything about each other besides a simple Message contract.

XAML for Xamarin.Forms

XAML—the eXtensible Application Markup Language—allows developers to define user interfaces in Xamarin.Forms applications using markup rather than code. XAML is never required in a Xamarin.Forms program but it is often more succinct than equivalent code, more visually coherent, and potentially toolable. XAML is particularly well suited for use with the popular MVVM (Model-View-ViewModel) application architecture: XAML defines the View that is linked to ViewModel code through XAML-based data bindings.
