Azure File Storage - Block on copy

Question

I see that there is a CloudFile.StartCopy() method but how can I block until it's complete? This example suggests calling StartCopy() and then calling destFile.DownloadText() which I assume would block but I don't want to redownload a potentially sizable file just to block.

Not sure if this answers the "Block" part, but this is something I have done in a similar situtation. I hope it helps.

   var target = _container.GetBlockBlobReference(targetItemName);

   // StartCopy will add a request to a queue, that's all
   target.StartCopy(source);

   // Now we poll the copy's status
   while (target.CopyState.Status == CopyStatus.Pending)
        await Task.Delay(500);

   if (target.CopyState.Status != CopyStatus.Success)
        throw new ApplicationException("Copy failed: " + target.CopyState.Status);
