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.

Implementing the producer/consumer pattern

The blocks in the TPL Dataflow library provide a fantastic platform for implementing the producer/consumer pattern. If you are not familiar with this design pattern, it involves two operations and a queue of work. The producer is the first operation. It is responsible for filling the queue with data or units of work. The consumer is responsible for taking items from the queue and acting on them in some way. There can be one or more producers and one or more consumers in the system. You can change the number of producers or consumers, depending on which part of the process is the bottleneck.

Real-World Scenario Example

To relate the producer/consumer pattern to a real-world scenario, think about preparing gifts for a holiday gathering. You and a partner are working together to prepare the gifts. You are fetching and staging the gifts to be wrapped. You are the producer. Your partner is taking items from your queue and wrapping each gift...
