By: Mark J. Price, Ovais Mehboob Ahmed Khan

Overview of this book

C# is a widely used programming language, thanks to its easy learning curve, versatility, and support for modern paradigms. The language is used to create desktop apps, background services, web apps, and mobile apps. .NET Core is open source and compatible with Mac OS and Linux. There is no limit to what you can achieve with C# and .NET Core. This Learning Path begins with the basics of C# and object-oriented programming (OOP) and explores features of C#, such as tuples, pattern matching, and out variables. You will understand.NET Standard 2.0 class libraries and ASP.NET Core 2.0, and create professional websites, services, and applications. You will become familiar with mobile app development using Xamarin.Forms and learn to develop high-performing applications by writing optimized code with various profiling techniques. By the end of C# 7 and .NET: Designing Modern Cross-platform Applications, you will have all the knowledge required to build modern, cross-platform apps using C# and .NET. This Learning Path includes content from the following Packt products: • C# 7.1 and .NET Core 2.0 - Modern Cross-Platform Development - Third Edition by Mark J.

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...
