Task-based Asynchronous Pattern - WaitAsync

Recently I was asked about a specific scenario when some code was being converted into using TAP and this was code that already used tasks. Since the existing code used the "IsFaulted" property a lot I came up with this little extension method making it easy to see if a task failed or not using the await keyword but without adding a lot of exception handling.

 1: public static Task<bool> WaitAsync(this Task task)

 2: {

 3:     var tcs = new TaskCompletionSource<bool>();

 4:     task.ContinueWith(

 5:         t => tcs.TrySetResult(!(t.IsFaulted || t.IsCanceled)));

 6:     return tcs.Task;

 7: }

or

public static Task<bool> WaitAsync(this Task task)

{

      return task.ContinueWith(

                       t => !(t.IsFaulted || t.IsCanceled),

                      TaskContinuationOptions.ExecuteSynchronously);

}
