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.

Introducing PLINQ

PLINQ is a set of .NET extensions for LINQ that allow part of the LINQ query to execute in parallel by leveraging the thread pool. The PLINQ implementation provides parallel versions of all of the available LINQ query operations.

Like LINQ queries, PLINQ queries offer deferred execution. This means that the objects are not queried until they need to be enumerated. If you aren’t familiar with LINQ’s deferred execution, we will look at a simple example to illustrate the concept. Consider these two LINQ queries:

internal void QueryCities(List<string> cities)
{
    // Query is executed with ToList call
    List<string> citiesWithS = cities.Where(s => 
        s.StartsWith('S')).ToList();
    // Query is not executed here
    IEnumerable<string> citiesWithT = cities.Where(s => 
...
