Parallel Programming and Concurrency with C# 10 and .NET 6

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.

Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “By calling ThreadPool.SetMaxThreads, you can change the maximum values for workerThreads and completionPortThreads.”

A block of code is set as follows:

public async Task PerformCalculations()
    _runningTotal = 3;
    await MultiplyValue().ContinueWith(async (Task) => {
        await AddValue();
    Console.WriteLine($”Running total is {_runningTotal}”);

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

    private async Task MultiplyValue()
        await Task.Delay(100);
        var currentTotal = Interlocked.Read(ref 
        Interlocked.Exchange(ref _runningTotal, 
            currentTotal * 10);

Any command-line input or output is written as follows:

$ mkdir css
$ cd css

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Let’s look at a quick example of how to implement this in our CancellationPatterns project.”
