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 6: Parallel Programming Concepts

The Task Parallel Library (TPL) encompasses various .NET programming constructs, including parallel loops, parallel invocations, PLINQ, and task-based async programming. In Chapter 5, we explored async programming with Task objects. This chapter will delve deeper into the System.Threading.Tasks.Parallel members in the TPL and some additional tasking concepts for handling related tasks.

The lines between parallel programming, concurrency, and asynchronous programming are not always clear-cut, and you will discover where the three concepts intersect as we read ahead.

In this chapter, you will learn the following:

  • Getting started with the TPL
  • Parallel loops in .NET
  • Relationships between parallel tasks
  • Common pitfalls with parallelism

By the end of this chapter, you will understand how to use parallel programming in your own projects, why you would choose a parallel loop over a standard loop, and when to use async...
