Parallel Programming and Concurrency with C# 10 and .NET 6

By: Alvin Ashcraft

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.

In this chapter, we learned about some tools and techniques to unit test .NET projects that contain different multithreaded constructs. We started by discussing the best methods for testing C# code that employs async/await. This will be common in modern applications, and it is important to have a suite of automated unit tests covering your async code.

We also walked through some examples of unit tests that test methods that leverage parallel constructs and concurrent data structures. In the last section of the chapter, we learned about dotMemory Unit from JetBrains. This free unit testing tool adds the ability to detect objects leaked by methods under test. It is a powerful automation tool for synchronous and asynchronous .NET code.

This is the final chapter. Thanks for following along on this multithreading journey. Hopefully, you didn’t encounter any deadlocks or race conditions along the way. This book provided guidance for your path through the modern, multithreaded...
