Is there a Task based replacement for System.Threading.Timer?

Question

I'm new to .Net 4.0's Tasks and I wasn't able to find what I thought would be a Task based replacement or implementation of a Timer, e.g. a periodic Task. Is there such a thing?

It depends on 4.5, but this works.

public class PeriodicTask
{
    public static async Task Run(Action action, TimeSpan period, CancellationToken cancellationToken)
    {
        while(!cancellationToken.IsCancellationRequested)
        {
            await Task.Delay(period, cancellationToken);

            if (!cancellationToken.IsCancellationRequested)
                action();
        }
     }

     public static Task Run(Action action, TimeSpan period)
     { 
         return Run(action, period, CancellationToken.None);
     }
}

Obviously you could add a generic version that takes arguments as well. This is actually similar to other suggested approaches since under the hood Task.Delay is using a timer expiration as a task completion source.
