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.

Checking for memory leaks with unit tests

Memory leaks are by no means unique to multithreaded code, but they certainly can happen. The more code that is executing in your application, the more likely it is that some objects are going to leak. The company that makes the popular .NET tools, ReSharper and Rider, also makes a tool called dotMemory for analyzing memory leaks. While these tools are not free, JetBrains does offer its memory unit testing tool for free. It’s called dotMemory Unit.

In this section, we will create a dotMemory Unit test to check whether we are leaking one of our objects. You can run these dotMemory Unit tests for free with .NET on the command line by downloading the standalone test runner here:
