Guide developers to implement robust and efficient asynchronous code in C#, covering Task/ValueTask returns, cancellation handling, parallelization, and Godot-specific patterns such as ToSignal and SceneTreeTimer.
Apply these guidelines to implement safe, efficient async methods in your C# projects and Godot integrations.

C# async code in Godot requires following established patterns for Task returns, cancellation tokens, and Godot-specific async usage like ToSignal and SceneTreeTimer to ensure correct and safe execution. Proper async void usage for signal handlers is also critical to prevent runtime crashes.
For C# public APIs, using Task or ValueTask return types is recommended. ValueTask provides better performance by reducing allocations in hot paths, while Task is suitable for general asynchronous operations. Consistent return types ensure predictable async behavior across your codebase.
Parallel execution and error handling in C# is achieved using Task.WhenAll and Task.WhenAny. Task.WhenAll waits for all tasks to complete and aggregates exceptions, while Task.WhenAny returns the first completed task, enabling patterns like racing operations or timeouts.
Yes, async void is specifically appropriate for Godot signal handlers in C#. The csharp-async guidelines specify proper async void usage for signal handlers, allowing you to safely fire asynchronous operations directly from Godot engine callbacks without blocking the main thread.
Cancellation token propagation in C# involves passing CancellationToken parameters through public async APIs and downstream method calls. This ensures cooperative cancellation, allowing long-running async operations to stop gracefully when requested, improving application responsiveness and resource management.
Yes, the C# async guidance applies to general C# applications and Godot game development scenarios. It specifies return types, exception handling, and performance considerations for Task-based asynchronous programming that are relevant across both environments.
