Csharp Async

github/awesome-copilot
10.1k installs38k stars
Summary

A solid code reviewer for async C# that catches the stuff that actually matters. It'll flag when you're mixing .Wait() with async code, remind you about ConfigureAwait(false) in library scenarios, and push you toward Task.WhenAll() instead of sequential awaits. The skill knows the difference between when to use ValueTask versus Task, and it won't let you get away with async void methods outside event handlers. Good for both fixing existing async code that's causing deadlocks and writing new async methods that follow TAP patterns correctly.
