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.

Asynchronous programming best practices

When working with async code, there are many best practices of which you should be aware. In this section, we will list the most important ones to remember in your day-to-day development. David Fowler, who is a veteran member of the ASP.NET team at Microsoft and a .NET expert, maintains an open source list of many other best practices. I recommend bookmarking this page for later reference while working with your own projects:

These are my top recommendations (in no particular order) to follow when working with async code:

  1. Always prefer async and await over synchronous methods and blocking calls such as Wait() and Result. If you are creating a new project, you should build with async in mind from the start.
  2. Unless you are using Task.WhenAll to wait for multiple operations simultaneously, you should directly await a...
