Fire and forget (ARCH103)

Key dotnet.async.fire-and-forget · Severity warning · Category async

A call returning a Task should be awaited or assigned to a variable. Otherwise exceptions are lost and execution continues before the work completes.

Incorrect

public async Task HandleAsync()
{
    _repository.SaveAsync();
    await _notifier.NotifyAsync();
}

Correct

public async Task HandleAsync()
{
    await _repository.SaveAsync();
    await _notifier.NotifyAsync();
}

Fix

Await the Task, or explicitly assign it to a variable if intentional. If needed, suppress the rule per project/workspace via except/ignore.
