Task extensions

The MADE.Threading.TaskExtensions class provides convenience methods for working with collections of tasks and handling task exceptions.

WhenAll and WhenAny on collections

Instead of calling Task.WhenAll(tasks.ToArray()), use the extension methods directly on an IEnumerable<Task>:

using MADE.Threading;

var tasks = items.Select(item => ProcessAsync(item));
await tasks.WhenAll();

var completedTask = await tasks.WhenAny();

These are thin wrappers around Task.WhenAll and Task.WhenAny, but they read more naturally when you're already working with a collection of tasks.

Observing exceptions with AndObserveExceptions

When you fire-and-forget a task, any exceptions it throws become unobserved. In .NET, unobserved task exceptions are eventually caught by the TaskScheduler.UnobservedTaskException handler, which can log warnings or, in older .NET versions, crash the process.

AndObserveExceptions ensures the task's exceptions are observed, and optionally executes a callback with the exception:

using MADE.Threading;

// Fire-and-forget with exception observation
_ = backgroundTask.AndObserveExceptions(ex =>
{
    logger.LogError(ex, "Background task faulted");
});

This is useful for tasks that you intentionally don't await but still want to handle errors from gracefully.
