SKILL.md

Proper async/await usage is critical for UI responsiveness and application stability. This skill covers patterns specific to WPF desktop applications.

| async void | Exceptions lost, can't await | Use async Task, except event handlers | | .Result / .Wait() | Deadlock on UI thread | await all the way | | Missing try-catch in commands | Unhandled exceptions crash | Wrap async commands | | Ignoring CancellationToken | Can't cancel operations | Pass token through chain |

| Fire-and-forget without logging | Silent failures | Use FireAndForget extension | | Task.Run for I/O | Wastes thread pool | Use async I/O APIs |
