Did you know that the .NET compiler turns our async methods into a struct? And that .NET adds a try/catch block to each of these classes, potentially hiding thrown exceptions? It's true!

In this session, we will learn how to best use async/await in C# by analyzing how .NET compiles our async code.

Join me as we take an existing app and optimize its async code together, showing off performance gains, better exception handling, improved run-time speed, and smaller app size!

NDC Conferences

A deep-dive conference talk transcript covering common async/await mistakes in .NET and how to fix them. Topics include how the .NET compiler generates IAsyncStateMachine code under the hood, why non-awaited tasks silently swallow exceptions, the dangers of async void (race conditions, uncatchable exceptions), the safe-fire-and-forget pattern, proper use of CancellationToken parameters, ConfigureAwait(false) for performance, blocking calls (.Wait()/.Result) vs the await keyword, IAsyncEnumerable for streaming data, and new .NET 8/9/10 features like ConfigureAwaitOptions and Task.ToAsyncEnumerable(). Practical code refactoring examples are shown using a .NET MAUI Hacker News reader app.
