Overview of this book

.NET has included managed threading capabilities since the beginning, but early techniques had inherent risks: memory leaks, thread synchronization issues, and deadlocks. This book will help you avoid those pitfalls and leverage the modern constructs available in .NET 6 and C# 10, while providing recommendations on patterns and best practices for parallelism and concurrency. Parallel, concurrent, and asynchronous programming are part of every .NET application today, and it becomes imperative for modern developers to understand how to effectively use these techniques. This book will teach intermediate-level .NET developers how to make their applications faster and more responsive with parallel programming and concurrency in .NET and C# with practical examples. The book starts with the essentials of multi-threaded .NET development and explores how the language and framework constructs have evolved along with .NET. You will later get to grips with the different options available today in .NET 6, followed by insights into best practices, debugging, and unit testing. By the end of this book, you will have a deep understanding of why, when, and how to employ parallelism and concurrency in any .NET application.

Discovering patterns for thread cancellation

There are different methods of listening for cancellation requests from a thread or task. So far, we have seen examples of managing these requests by either handling the OperationCanceledException type or checking the value of IsCancellationRequested. The pattern of checking IsCancellationRequested, usually inside a loop, is called polling. First, we will see another example of this pattern. The second pattern we will examine is receiving the notification by registering a callback method. The final pattern that we will cover in this section is listening to cancellation requests with wait handles using ManualResetEvent or ManualResetEventSlim.

Let’s start by trying another example of handling a cancellation request by polling.

Canceling with polling

In this section, we will create another example that uses polling to cancel a background task. The previous example of polling was running in a background thread on the ThreadPool...
