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.

Introducing async in ASP.NET MVC core

async and await are code markers that help us write asynchronous code using TPL. They help maintain the structure of code and make it look synchronous while processing code asynchronously in the background.

We introduced async and await in Chapter 9, Async, Await, and Task-Based Asynchronous Programming Basics.

Now, let's create an asynchronous web API with ASP.NET Core 3.0 and VS 2019 preview. The API will read a file from the server:

  1. Open Visual Studio 2019 to be presented with the following screen. Create a new ASP.NET Core Web Application project in VS 2019, as shown in the following screenshot:
  1. Give the project a name and the location where you want it to be created:
  1. Select the project's type, which in our case is API, and click Create:
  1. Now, create a new folder in our project called Files and add a file named data...
