High-Performance Programming in C# and .NET

By: Jason Alls

Overview of this book

Writing high-performance code while building an application is crucial, and over the years, Microsoft has focused on delivering various performance-related improvements within the .NET ecosystem. This book will help you understand the aspects involved in designing responsive, resilient, and high-performance applications with the new version of C# and .NET. You will start by understanding the foundation of high-performance code and the latest performance-related improvements in C# 10.0 and .NET 6. Next, you’ll learn how to use tracing and diagnostics to track down performance issues and the cause of memory leaks. The chapters that follow then show you how to enhance the performance of your networked applications and various ways to improve directory tasks, file tasks, and more. Later, you’ll go on to improve data querying performance and write responsive user interfaces. You’ll also discover how you can use cloud providers such as Microsoft Azure to build scalable distributed solutions. Finally, you’ll explore various ways to process code synchronously, asynchronously, and in parallel to reduce the time it takes to process a series of tasks. By the end of this C# programming book, you’ll have the confidence you need to build highly resilient, high-performance applications that meet your customer's demands.

Creating threads and using parameters

In this section, we look at the creation of threads. First, we will see how to create parameterless threads in the foreground and the background. Let’s define both foreground and background threads as follows:

  • Foreground threads: By default, threads run in the foreground. A process will continue to run if, at least, one foreground thread is running. Should the Main method be complete and the foreground thread is still running, the process will remain active until the foreground thread terminates.
  • Background threads: Background threads are created in the same way as foreground threads. The main difference is that you must explicitly set the thread to run in the background.

The following code shows how to create and run a foreground thread:

var foregroundThread = new Thread(methodName);
foregroundThread.Start();

To create and run a background thread, you run the following code:

var backgroundThread = new Thread...
