Overview of this book

If you want to build powerful cross-platform applications with C# 7 and .NET Core, then this book is for you. First, we’ll run you through the basics of C#, as well as object-oriented programming, before taking a quick tour through the latest features of C# 7 such as tuples, pattern matching, out variables, and so on. After quickly taking you through C# and how .NET works, we’ll dive into the .NET Standard 1.6 class libraries, covering topics such as performance, monitoring, debugging, serialization and encryption. The final section will demonstrate the major types of application that you can build and deploy cross-device and cross-platform. In this section, we’ll cover Universal Windows Platform (UWP) apps, web applications, mobile apps, and web services. Lastly, we’ll look at how you can package and deploy your applications so that they can be hosted on all of today’s most popular platforms, including Linux and Docker. By the end of the book, you’ll be armed with all the knowledge you need to build modern, cross-platform applications using C# and .NET Core.

Preface

Chapter 15 - Building Mobile Apps Using Xamarin.Forms and ASP.NET Core Web API


  1. How does ASP.NET distinguish a request for MVC from a request for Web API?

    • Multiple entries are added to the route table. By convention, Web API controllers should use attributes to register routes that look for URLs that begin with api/. If a URL doesn't begin with api/ then it should match other routes registered by MVC.

  2. What data formats does Web API support by default?

    •  x-www-formurlencoded, JSON, and XML.

  3. What is the difference between Xamarin and Xamarin.Forms?

    • Xamarin allows developers to build native iOS, Android, and Windows apps using existing skills, teams, and code written in C# and .NET. But the user interfaces must be developed specifically for each platform. Xamarin.Forms allows developers to build native user interfaces for iOS, Android and Windows from a single, shared C# codebase using XAML.

  4. What types of cell are supported by the ListView?

    • Data in a ListView is presented in cells. TextCell displays a string of text, optionally with a second line in smaller font with an accent color. ImageCell displays an image on the left with text. SwitchCell and EntryCell can be used, but this is rare. Custom cells can also be defined.
