C# 7 and .NET: Designing Modern Cross-platform Applications

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. Price • C# 7 and .NET Core 2.0 High Performance by Ovais Mehboob Ahmed Khan

Understanding async and await


C# 5 introduced two keywords to simplify working with the Task type. They are especially useful for the following:

  • Implementing multitasking for a graphical user interface (GUI)
  • Improving the scalability of web applications and web services

In Chapter 10, Building Web Sites Using ASP.NET Core MVC, and in Chapter 11, Building Web Services and Applications Using ASP.NET Core, we will explore how the async and await keywords can improve scalability in websites, web services, and web applications.

In Chapter 12, Building Windows Apps Using XAML and Fluent Design, and in Chapter 13, Building Mobile Apps Using XAML and Xamarin.Forms, we will explore how the async and await keywords can implement multitasking with a GUI running on Universal Windows Platform and Xamarin.

For now, let's learn the theory of why these two C# keywords were introduced, and then later you will see them used in practice.

Improving responsiveness for console apps
