End to-end native iOS, Android and Windows apps wtih Xamarin

Presentation given at TechUnder 20 Pre-Hackathon event giving an overview of how to use Xamarin using Visual Studio 2015. Also has an overview of the Xamarin Evolve 2016 conference and summary of Mobile Ate the World presentation.

Xamarin allows developers to write native iOS, Android, and Windows apps using C# with a shared codebase. It works by compiling C# code into the native platform code, translating .NET into Objective-C for iOS and bridges for Android. Xamarin.Forms provides common UI elements and pages that can be reused across platforms, reducing the amount of platform-specific code needed. Key pages include ContentPage, MasterDetailPage, NavigationPage, TabbedPage, and CarouselPage. Layouts like StackLayout, GridLayout, and RelativeLayout are used to compose user interface controls.

Xamarin enables C# devs to become native iOS, Android, and Windows mobile app dev overnight. Learn how to leverage your existing .NET and C# skills to create iOS and Android mobile apps in Visual Studio. In addition to allowing you to write your iOS and Android apps in C#, Xamarin lets you reuse existing .NET libraries and share your business logic across iOS, Android, and Windows apps. During this session we cover the Xamarin platform and how to create native iOS, Android, and Windows apps in C#. See what’s new and next for Xamarin development inside of Visual Studio. Moreover, we focus on the code, with several live coding adventures throughout the entire session and show you the latest and greatest in native cross-platform development.

Xamarin allows developers to build native mobile apps for Android, iOS, and Windows from shared C# code. Developers can share all business logic and UI code across platforms using Xamarin.Forms, or share just business logic using traditional Xamarin. It supports building UIs with common UI elements and controls and data binding. Platform-specific code can interface with shared code through NuGet packages, shared projects, or portable class libraries. Xamarin apps can be built and deployed to emulators and devices from Microsoft Visual Studio on Windows or Visual Studio for Mac.

This document discusses how to build connected mobile apps using Microsoft Azure. It provides an overview of Azure services for mobile backends such as REST APIs, offline sync, push notifications, and authentication. It also provides code samples for creating a mobile backend, defining and syncing tables, and querying local data. The document promotes Xamarin for building native and cross-platform mobile apps with shared C# code and recommends resources for getting started with Xamarin on Azure.

This document discusses Xamarin, a platform for building mobile apps using C# and .NET. It can be used to build apps for iOS, Android, and Windows Phone from shared C# code, while still allowing full access to native platform APIs. The document promotes features like hot reloading for faster development cycles and high performance from ahead-of-time compilation to ARM binaries or just-in-time compilation. Statistics are provided on code reuse between platforms for sample Xamarin apps. James Montemagno of Xamarin encourages questions from attendees.

Xamarin is an open source app platform from Microsoft that allows developers to build high-performance, native iOS, Android, and other mobile apps using C# and .NET. It enables developers to maximize code reuse by sharing C# code across platforms while retaining full access to native platform APIs. Apps are compiled to native ARM code for high performance, while the shared code approach streamlines development. Xamarin includes features like Xamarin.Forms for cross-platform UIs and Xamarin.Essentials for accessing common device capabilities through a shared API.

The document discusses different approaches to mobile cross-platform development including web apps, hybrid apps, and native apps. It then focuses on the Xamarin platform, which allows developers to build fully native mobile apps for Android and iOS using C# and .NET with a single shared codebase. Xamarin apps are compiled to native code for each platform and provide access to all native platform features and APIs.

Join James as he walks through his latest creation, Island Tracker(https://islandtracker.app) for Animal Crossing on iOS and Android. Built full cross-platform with Xamarin.Forms and leveraging Azure Functions and Table Storage as the cloud backend he will discuss his full architecture and demo how it all was pulled together. He will talk about lessons learned, preparing for release, continuous integration, user testing, and more! If you have ever wanted an insight into creating and deploying a cloud connected app then join in.

Rob Gibbens shows you how to build better Xamarin.Forms UI using platform-specific APIs that aren’t directly exposed by the framework. He’ll demo how to integrate native controls and adjust visual properties that are unique to each platform while still sharing the majority of your code across platforms. You’ll leave ready with the step-by-step guidance you need to take full advantage of the latest OS-specific UI patterns and designs.

Silicon Valley iOS Developers meetup (18-Apr-16) talk about using Xamarin to develop iPhone apps in Visual Studio with C#.

A quick 30-60 minute overview of the announcements from the Xamarin Evolve 2016 conference. This was used to provide the talking points for a user group presentation

This document discusses Xamarin, a platform that allows developers to write and test mobile apps using C# and .NET. It can be used to build apps for iOS, Android, and Windows from shared C# code. Xamarin allows building native UIs for each platform while sharing most of the app logic. It includes features like Xamarin.Forms for building cross-platform UIs. The document also covers how Xamarin integrates with Visual Studio and supports latest mobile platforms and APIs.

This session talks about evolution of Mono and Xamarin and some pretty cool demo of how to leverage your .NET skills to develop iPhone and Android applications.

Leveraging C# and it’s awesome features to developer iOS and Android apps with Xamarin allows for rapid application development, but how can you go even further. In this session we will take a look at tools, libraries, and other resources to increase productivity enabling you to write less code and share more code across all of your apps. We will additionally dive through everything new in Xamarin.Forms and several tools that Forms has built in to help with cross platform development. No matter how you are developing applications with Xamarin you will be sure to find something new and fun to use on a day to day basis.

XamarinDevDays covered the traditional Xamarin approach of writing separate UI code for each platform versus using Xamarin.Forms which allows for more code sharing with a single shared UI code and backend. Xamarin.Forms was discussed in depth including over 40 pages, layouts and controls that are built from code behind or XAML, two-way data binding, navigation, animation API and more. Examples were provided of XAML code for a tabbed page app with login functionality to demonstrate how Xamarin.Forms can be used to build full apps with shared UI and backend code across platforms.

Video: http://channel9.msdn.com/Shows/Visual-Studio-Toolbox/VS-Toolbox-Xamarin-Forms Robert welcomes James Montemagno, a developer evangelist at Xamarin, back on the show for another series on building cross-platform apps with Xamarin and C#. In this episode, part one of four, we take a look at Xamarin.Forms, a cross-platform UI toolkit that sits on top of Xamarin.iOS, Xamarin.Android, and Windows Phone. We will see how to share not only the business logic of an application, but also how to build a fully native cross-platform UI completely in XAML, including features such as data binding, styles, and triggers.
