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.

Testing tools

One of the most important tools in Visual Studio to run a test or see the results of test execution is Test Explorer. We had a brief look at Test Explorer at the start of this chapter. One key feature of Test Explorer is its ability to run test cases in parallel. If you have a system with multiple cores, you can easily take advantage of parallelism to run test cases faster. This can be done by clicking on the Run Tests in parallel toolbar button in Test Explorer:

Depending on your version of Visual Studio, some additional support is provided by Microsoft. One useful tool is the option to generate unit test cases automatically using Intellitest. Intellitest analyzes your source code and automatically generates test cases, test data, and test suites. Intellitest isn't supported in .NET core yet, though it's available for other versions of the .NET Framework...
