Overview of this book

C# 7.1 and .NET Core 2.0 – Modern Cross-Platform Development, Third Edition, is a practical guide to creating powerful cross-platform applications with C# 7.1 and .NET Core 2.0. It gives readers of any experience level a solid foundation in C# and .NET. The first part of the book runs you through the basics of C#, as well as debugging functions and object-oriented programming, before taking a quick tour through the latest features of C# 7.1 such as default literals, tuples, inferred tuple names, pattern matching, out variables, and more. After quickly taking you through C# and how .NET works, this book dives into the .NET Standard 2.0 class libraries, covering topics such as packaging and deploying your own libraries, and using common libraries for working with collections, performance, monitoring, serialization, files, databases, and encryption. The final section of the book demonstrates the major types of application that you can build and deploy cross-device and cross-platform. In this section, you'll learn about websites, web applications, web services, Universal Windows Platform (UWP) apps, and mobile apps. 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.

Developing for the web is developing with HTTP.

Understanding HTTP

To communicate with a web server, the client, aka user agent, makes calls over the network using a protocol known as Hypertext Transfer Protocol (HTTP). HTTP is the technical underpinning of the web. So, when we talk about web applications or web services, we mean that they use HTTP to communicate between a client (often a web browser) and a server.

A client makes an HTTP request for a resource, such as a page identified by a Uniform Resource Locator (URL), and the server sends back an HTTP response, as shown in the following diagram:

You can use Google Chrome and other browsers to record requests and responses.

Note

Good PracticeGoogle Chrome is available on more operating systems than any other browser, and it has powerful, built-in developer tools, so it is a good first choice of browser. Always test your web application with Chrome and at least two other browsers, for example, Firefox and either...
