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.

IIS and Kestrel in ASP.NET Core

In the previous chapter, we discussed writing unit test cases for parallel and asynchronous code. We also discussed three unit testing frameworks that are available in Visual Studio: MSUnit, NUnit, and xUnit.

In this chapter, we will introduce how the threading model works with Internet Information Services (IIS) and Kestrel. We will also look at various tweaks we can make to take maximum advantage of resources on a server. We will introduce the working model of Kestrel and how we can take advantage of parallel programming techniques while creating microservices.

In this chapter, we will cover the following topics:

  • The IIS threading model and internals
  • The Kestrel threading model and internals
  • Introduction to best practices of threading in microservices
  • Introduction to async in ASP.NET MVC Core
  • Async streams (new in .NET Core 3.0)
