Parallel Programming and Concurrency with C# 10 and .NET 6

By: Alvin Ashcraft

Overview of this book

.NET has included managed threading capabilities since the beginning, but early techniques had inherent risks: memory leaks, thread synchronization issues, and deadlocks. This book will help you avoid those pitfalls and leverage the modern constructs available in .NET 6 and C# 10, while providing recommendations on patterns and best practices for parallelism and concurrency. Parallel, concurrent, and asynchronous programming are part of every .NET application today, and it becomes imperative for modern developers to understand how to effectively use these techniques. This book will teach intermediate-level .NET developers how to make their applications faster and more responsive with parallel programming and concurrency in .NET and C# with practical examples. The book starts with the essentials of multi-threaded .NET development and explores how the language and framework constructs have evolved along with .NET. You will later get to grips with the different options available today in .NET 6, followed by insights into best practices, debugging, and unit testing. By the end of this book, you will have a deep understanding of why, when, and how to employ parallelism and concurrency in any .NET application.

In this chapter, we learned some useful techniques for improving client application performance. We started by exploring some different uses of async and await in the ViewModel of a WPF application. In that project, we saw that awaiting Task.WhenAll does not block the main thread, which keeps the UI responsive to user input. We discussed how Task.Run and Task.Factory.StartNew can be used to call synchronous code from asynchronous code, making it easier to introduce managed threading to existing applications. We finished up the chapter by learning some techniques to update the UI thread from other threads without causing exceptions at runtime.

You should be feeling more comfortable using async, await, and the TPL in your code after reading this chapter. Try taking what you have learned here and start adding some async code to your own client applications. For additional reading on async and await, you can check out this C# article on Microsoft Docs:
