Async Await Best Practices

Learn how to master asynchronous programming with async await in C#

Extensions for System.Threading.Tasks Includes extension methods to safely fire-and-forget a Task and/or a ValueTask Includes WeakEventManger which avoids memory leaks when events are not unsubscribed

Async Extensions for ICommand Includes AsyncCommand and IAsyncCommand which allows ICommand to safely be used asynchronously with Task. Includes AsyncValueCommand and IAsyncValueCommand which allows ICommand to safely be used asynchronously with ValueTask

All the courses you need to learn and master .NET MAUI

When using async await we inevitably have to mark methods as async void. This leads to a lot of issues for programmers…

Explore an overview of the C# language support for asynchronous programming by using async, await, Task, and Task.

Learn about the .NET thread pool that provides background worker threads

The .NET Framework 4 saw the introduction of the System.Threading.Tasks namespace, and with it the Task class. This type and the derived Task<TResult> have long since become a staple of .NET programming, key aspects of the asynchronous programming model introduced with C# 5 and its async / await keywords. In this post, I’ll cover the newer ValueTask/ValueTask<TResult> types, which were introduced to help improve asynchronous performance in […]

I’ve been asked a few times recently various questions about ExecutionContext and SynchronizationContext, for example what the differences are between them, what it means to “flow” them, and how they relate to the new async/await keywords in C# and Visual Basic. I thought I’d try to tackle some of those questions here. WARNING: This post […]

This is an essential truth of async in its purest form: There is no thread.

Changes in ConfigureAwait that are new with .NET 8.0.

In this post I look at how the new Task.WaitAsync() API is implemented in .NET 6, looking at the internal types used to implement it

Introduction In modern distributed .NET applications, managing context across execution boundaries is a critical architectural concern. While both AsyncLocal<T> and ThreadLocal<T> provide mechanisms for maintaining contextual data, their implementations and use cases differ significantly in ways that impact system architecture, performance, and maintainability. This comprehensive guide explores both
