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 8: Parallel Data Structures and Parallel LINQ

.NET provides many useful features and data constructs for developers who are introducing parallelism to their projects. This chapter will explore these features, including concurrent collections, the SpinLock<T> synchronization primitive, and Parallel LINQ (PLINQ). These features can improve the performance of your applications while maintaining safe threading practices.

Most .NET developers are familiar with LINQ frameworks, including LINQ to Objects, LINQ to SQL, and LINQ to XML. There are even open source .NET LINQ libraries, such as LINQ to Twitter ( We will take those LINQ skills and leverage them in parallel programming with PLINQ. Every LINQ developer can be a PLINQ developer after reading this chapter. Read ahead for some useful examples of working with PLINQ in C#.

In this chapter, you will learn about the following:

  • Introducing PLINQ
  • Converting LINQ queries...
