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.

Updating the UI thread without exceptions

When working with managed threading in .NET applications, there are many pitfalls that developers must learn to avoid. One of the common mistakes developers make is writing code that updates a UI control in a Windows application from a non-UI thread. This kind of error will not be detected by the compiler. Developers will receive a runtime error indicating that a control created on the main thread cannot be modified on another thread.

So, how do you avoid these runtime errors? The best way to avoid them is by not updating UI controls from background threads at all. WPF helps avoid the problem with the MVVM pattern and data binding. Binding updates are automatically marshaled to the UI thread by .NET. You can safely update properties in your ViewModel classes from a background thread without causing errors at runtime.

If you are updating UI controls directly in your code, either in a WinForms application or in the code-behind file of a...
