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 XAMLBuild 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

XamarinThe Ultimate Beginner's Guide to Learn Xamarin Step by Step The entire world is now surrounded by billions and trillions of mobile Tech which is inevitable. The major share of the development of mobile apps is taken by the Google's Android, Apple's iOS, and Microsoft's Windows. Every new learner or newbie in Mobile Development Domain finds himself in the dilemma of choosing the platform to start with. They are actually looking for a platform to execute or implement the test apps on something different from what it is intended for.Xamarin is one of the solutions to it which actually is meant for cross-platform mobile app development where you can build Android, iOS, and Windows native application using a single codebase. This single platform is C#. The apps developed using Xamarin performs almost similar to the native Platform applications.Working of XamarinXamarin has entirely converted the Android and iOS SDK to C# to make it more familiar to the developers. One can easily use the same codebase for both the platforms without the hassle of remembering the syntax of different languages all the time. Besides, the User Interface(UI) remains almost same. It has to be separately built for both the platforms and then has to be bound by the common codebase.There are actually two ways for building the User Interface. First one is using the original native methods to build the UI. Another one incorporates the use of Xamarin.Forms. These forms can be used to build UI for different platforms all at once and have almost 100% code sharing if these are chosen over Native UI Technology.After doing all the UI work comes the most challenging phase which is connecting the UI to the codebase. This connection can again be implemented using two code sharing approaches which are:1.Shared Project2.Portable Class Libraries(PCL)Xamarin.FormsXamarin provides developers two ways to build a mobile app. Either by using Xamarin.iOS and Xamarin.Android(main approach) or by using Xamarin.Forms which is a framework for simple apps and prototypes. Xamarin.Forms, the Visual Studio Library facilitates for rapid prototyping or building apps with few platform-specific functionalities. This makes Xamarin.Forms, the best fit, for apps considering code sharing more significant than custom UI. The developer need not design for each platform individually. With Xamarin.Forms, a single interface would be shared across platforms. Apps with some parts of the UI created using Xamarin.Forms and rest using native UI Toolkit can also be built using this approach.What Is 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, Windows, and Windows Phone.PerformanceXamarin apps are fully native so in xamarin you can enjoy fully native performance with shared code.Xamarin.iOS and Xamarin.Android (Separate UI)For Xamarin.iOS and Xamarin.Android, you have shared code base in C# .This business logic is shared across platforms and UI is separate for all platforms. This is separate UI approach. Xamarin.ios and Xamarin.Android give you 100% API coverage with benefits of .NET APIs. Anything you can do in Android or in iOS, you can do with Xamarin using C#.WindowsWindows already supports C# for development. So, it is also built in C# with native APIs.Xamarin.FormsXamarin.forms allow you more code sharing that you can also share application UI in all platforms.Included in Xamarin.FormsUI building blocks like pages, layouts, and controlsXAML-defined UIData bindingNavigationAnimation APIDependency ServiceMessaging CenterAdvantages of Xamarin.FormsNative appsShared Business LogicShared UIOne Xamarin development team require to develop apps for multiple platformsLess development time
