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.

Chapter 11: Canceling Asynchronous Work

In the previous chapters, we’ve looked at a few examples of how to cancel threads and tasks. This chapter will explore more of the methods available to cancel concurrent and parallel work with C# and .NET. The methods in this chapter will provide alternative ways to cancel background operations using callbacks, polling, and wait handles. You will gain a deeper understanding of how to safely cancel asynchronous work with a variety of methods using some practical scenarios.

In this chapter, you will learn about the following topics:

  • Canceling managed threads
  • Canceling parallel work
  • Discovering patterns for thread cancellation
  • Handling multiple cancelation sources

By the end of this chapter, you will understand how to cancel different types of asynchronous and parallel tasks.
