Overview of this book

In C# 9 and .NET 5 – Modern Cross-Platform Development, Fifth Edition, expert teacher Mark J. Price gives you everything you need to start programming C# applications. This latest edition uses the popular Visual Studio Code editor to work across all major operating systems. It is fully updated and expanded with a new chapter on the Microsoft Blazor framework. The book’s first part teaches the fundamentals of C#, including object-oriented programming and new C# 9 features such as top-level programs, target-typed new object instantiation, and immutable types using the record keyword. Part 2 covers the .NET APIs, for performing tasks like managing and querying data, monitoring and improving performance, and working with the file system, async streams, serialization, and encryption. Part 3 provides examples of cross-platform apps you can build and deploy, such as websites and services using ASP.NET Core or mobile apps using Xamarin.Forms. The best type of application for learning the C# language constructs and many of the .NET libraries is one that does not distract with unnecessary application code. For that reason, the C# and .NET topics covered in Chapters 1 to 13 feature console applications. In Chapters 14 to 20, having mastered the basics of the language and libraries, you will build practical applications using ASP.NET Core, Model-View-Controller (MVC), and Blazor. By the end of the book, you will have acquired the understanding and skills you need to use C# 9 and .NET 5 to create websites, services, and mobile apps.

Monitoring performance and resource usage

Before we can improve the performance of any code, we need to be able to monitor its speed and efficiency in order to record a baseline that we can then measure improvements from.

Evaluating the efficiency of types

What is the best type to use for a scenario? To answer this question, we need to carefully consider what we mean by best, and through this, we should consider the following factors:

  • Functionality: This can be decided by checking whether the type provides the features you need.
  • Memory size: This can be decided by the number of bytes of memory the type takes up.
  • Performance: This can be decided by how fast the type is.
  • Future needs: This depends on the changes in requirements and maintainability.

There will be scenarios, such as when storing numbers, where multiple types have the same functionality, so we will need to consider memory and performance to make a choice.

If we need to...
