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.

Manipulating data from multiple data sources

A JoinBlock can be configured to receive different data types from two or three data sources. As each set of data types is completed, the block is completed with a Tuple containing all three object types to be acted upon. In this example, we will create a JoinBlock that accepts a string and int pair and passes Tuple(string, int) along to an ActionBlock, which outputs their values to the console. Follow these steps:

  1. Start by creating a new console application in Visual Studio
  2. Add a new class named DataJoiner to the project and add a static method to the class named JoinData:
    public static void JoinData()
  3. Add the following code to create two BufferBlock objects, a JoinBlock<string, int>, and an ActionBlock<Tuple<string, int>>:
    var stringQueue = new BufferBlock<string>();
    var integerQueue = new BufferBlock<int>();
    var joinStringsAndIntegers = new JoinBlock<string,
