Hands-On Parallel Programming with C# 8 and .NET Core 3

By: Shakti Tanwar

Overview of this book

In today’s world, every CPU has a multi-core processor. However, unless your application has implemented parallel programming, it will fail to utilize the hardware’s full processing capacity. This book will show you how to write modern software on the optimized and high-performing .NET Core 3 framework using C# 8. Hands-On Parallel Programming with C# 8 and .NET Core 3 covers how to build multithreaded, concurrent, and optimized applications that harness the power of multi-core processors. Once you’ve understood the fundamentals of threading and concurrency, you’ll gain insights into the data structure in .NET Core that supports parallelism. The book will then help you perform asynchronous programming in C# and diagnose and debug parallel code effectively. You’ll also get to grips with the new Kestrel server and understand the difference between the IIS and Kestrel operating models. Finally, you’ll learn best practices such as test-driven development, and run unit tests on your parallel code. By the end of the book, you’ll have developed a deep understanding of the core concepts of concurrency and asynchrony to create responsive applications that are not CPU-intensive.

PLINQ is a parallel implementation of the Language Integrate Query (LINQ). PLINQ was first introduced in .NET Framework 4.0 and since then has been made feature-rich. Before LINQ, it was difficult for developers to fetch data from various data sources such as XML or databases as each source required different skills. LINQ is a language syntax that relies on .NET delegates and built-in methods to query or modify data without having to worry about learning low-level tasks.

In this chapter, we will start by understanding the LINQ providers in .NET. With PLINQ being the preferred choice for programmers, we will cover its various programming aspects, along with some disadvantages associated with it. Finally, we will understand the factors that affect the performance of PLINQ.

We will cover the following topics:

  • LINQ providers in .NET
  • Writing PLINQ queries
  • Preserving order...
