An important aspect of parallel programming is task coordination. While creating tasks, you may come across a producer/consumer scenario where a thread (the consumer) is waiting for a shared resource to be updated by another thread (the producer). Since the consumer doesn't know when the producer is going to update the shared resource, it keeps on polling the shared resource, which can lead to race conditions. Polling is highly inefficient in dealing with these scenarios. It is better to use the signaling primitives that are provided by the .NET Framework. With signaling primitives, the consumer thread is paused until it receives a signal from the producer thread. Let's discuss some common signaling primitives, such as Thread.Join, WaitHandles, and EventWaitHandlers.

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.
