Desenvolver aplicativos multiplataformas se tornou uma tarefa muito mais simples com Xamarin e com Xamarin Forms, frameworks para desenvolvimento de aplicações mobile. São ferramentas com boa estabilidade e consistência, com uma curva de aprendizado muito tênue. O desenvolvimento de páginas para os dispositivos pode ser feito em arquivos XAML e/ou por meio de classes C#, com diversos recursos, como layout e gerenciadores de conteúdo, entre outros que você conhecerá aqui. Neste livro, Everton Coimbra demonstra na prática como criar uma aplicação para iOS e Android com Xamarin e Xamarin Forms, utilizando a linguagem C#. Você vai desenvolver um projeto de exemplo que lidará com cadastro, imagens e base de dados, aplicando o modelo MVVM (Model, View, ViewModel). Para o acesso à base de dados, será feito uso do Entity Framework Core, API da Microsoft para persistência de objetos em um paradigma relacional. O autor ainda complementa o material com a implementação de serviços REST em um servidor Web, para serem consumidos em sua aplicação Xamarin. Tudo isso em uma arquitetura bem elaborada e flexível, que você poderá comprovar. Edição atualizada em 08/2021: Atualização para a versão 4.5.0.495 do Xamarin Forms.

Learn how to use the popular MVVM Light development framework with a focus on reliable, maintainable code that can be deployed across any of the .NET-supported mobile platforms. Clear examples are provided of the advantages of the MVVM platform along with step-by-step demonstrations of how to create applications at different levels of complexity. Application development is covered for iOS, Android, and Windows phone (UWP) using MVVM Light as the central framework. The model-view-view-model (MVVM) pattern is valued by many developers as an excellent way to create sophisticated modern applications. Its clear separation of presentation and business logic produces a clean implementation that promotes speed, scalability, and code reuse in applications with a complex UI. These characteristics have long been highly valued by WPF developers, and now that benefit is available to Xamarin developers, too. What You'll Learn Set up and install MVVM Light Understand the advantages and disadvantages of MVVM Discover why inversion of control is important in MVVM Conduct unit testing of MVVM apps Convert your existing apps to use MVVM Use MVVM Light within a Xamarin Forms app Use webservices Be introduced to the new .NET 2.0 Standard Class Library and how to use MVVM Light with it

Leverage Xamarin.Forms to build iOS and Android apps using a single, cross-platform approach. This book is the XAML companion to the C# guide Xamarin Mobile Application Development. You'll begin with an overview of Xamarin.Forms, then move on to an in-depth XAML (eXtensible Application Markup Language) primer covering syntax, namespaces, markup extensions, constructors, and the XAML standard. XAML gives us both the power of decoupled UI development and the direct use of Xamarin.Forms elements. This book explores the core of the Xamarin.Forms mobile app UI: using layouts and FlexLayouts to position controls and views to design and build screens, formatting your UI using resource dictionaries, styles, themes and CSS, then coding user interactions with behaviors, commands, and triggers. You'll see how to use XAML to build sophisticated, robust cross-platform mobile apps and help your user get around your app using Xamarin.Forms navigation patterns.Building Xamarin.Forms Mobile Apps Using XAML explains how to bind UI to data models using data binding and using the MVVM pattern, and how to customize UI elements for each platform using industry-standard menus, effects, custom renderers, and native view declaration. What You Will Learn Create world-class mobile apps for iOS and Android using C# and XAML Build a XAML UI decoupled from the C# code behind Design UI layouts such as FrameLayout, controls, lists, and navigation patterns Style your app using resource dictionaries, styles, themes, and CSS Customize controls to have platform-specific features using effects, custom renderers, and native views Who This Book Is For XAML and C# developers, architects, and technical managers as well as many Android and iOS developers

Xamarin is an abstraction layer that manages communication of shared code with underlying platform code. Xamarin runs in a managed environment that provides conveniences such as memory allocation and garbage collection. Xamarin enables developers to share an average of 90% of their application across platforms.
