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.

Introduction to concurrency

So, what is concurrency and how does it relate to parallelism in the context of C# and .NET? The terms are frequently used interchangeably, and if you think about it, they do have similar meanings. When multiple threads are executing in parallel, they are running concurrently. In this book, we will use the term concurrency when discussing patterns to follow when designing for managed threading. Additionally, we will discuss concurrency in the context of the concurrent collections that were introduced to .NET developers in .NET Framework 4.0. Let’s start by learning about the concurrent collections in the System.Collections.Concurrent namespace.

.NET has several collections that have been created with thread safety built-in. These collections can all be found in the System.Collections.Concurrent namespace. In this section, we will introduce five of the collections. The remaining three are variations of Partitioner. These will be explored in Chapter...
