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.

Chapter 12: Unit Testing Async, Concurrent, and Parallel Code

Unit testing asynchronous, concurrent, and parallel code can be a challenge for .NET developers. Fortunately, there are some steps you can take to help ease the difficulty. This chapter will provide some concrete advice and useful examples of how developers can unit test code that leverages multi-threaded constructs. These examples will illustrate how unit tests can still be reliable while covering code that performs multithreaded operations. In addition, we will explore a third-party tool that facilitates the creation of automated unit tests that monitor your code for potential memory leaks.

Creating unit tests for your .NET projects is important to maintain the health of your code base as it grows and evolves. When developers make changes to code that has unit test coverage, they can run the existing tests to feel confident that no existing functionality has been broken by the code changes. Visual Studio makes it simple...
