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.

Handling static objects

When working with static data in .NET, there are some important things to understand when it comes to managed threading.

Static data and constructors

One important item to understand about accessing static data from managed threads relates to constructors. Before a static member of any class can be accessed, its static constructor must first finish running. The runtime will block thread execution until the static constructor has run to ensure that all required initialization has finished.

If you are using static objects within your own code base, you will know which classes have static constructors and can control the complexity of the logic inside them. When the static data is outside of your control, inside a third-party library or .NET itself, things may not be so clear.

Let’s try a quick example to illustrate the potential delays that can be encountered in this scenario.
