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.

Getting started with the TPL

The TPL consists of the types that were added to the System.Threading and System.Threading.Tasks namespaces in .NET Framework 4.0. The TPL provides features that make parallelism and concurrency simpler for .NET developers. There is no need to manage the ThreadPool tasks in your code. The TPL handles thread management and automatically scales the number of active threads based on processor capability and availability.

Developers should use the TPL when they need to introduce parallelism or concurrency to their code for improved performance. However, the TPL is not the right choice for every scenario. How do you know when to choose the TPL and which TPL constructs are the best choice for each scenario?

Let’s explore a few common scenarios.

I/O-bound operations

When dealing with I/O-bound operations such as file operations, database calls, or web service calls, asynchronous programming with Task objects and C# async/await operations are...
