[BUG] using OpenWriteAsync with BlockBlobClient does not seems to reuse the BlobClientOptions.Retry options

Library name and version

Azure.Storage.Blobs 12.13.0

Describe the bug

I’m using BlobClientOptions to add a different retry. It does not seem to be applied to the BlockBlobClient.

public async Task UploadToBlobAsync(string blobSasUrl, Stream sourceStream, CancellationToken cancellationToken)
        {
            BlockBlobClient blob = new(new Uri(blobSasUrl), new BlobClientOptions
            {
                Retry =
                {
                    Mode = RetryMode.Fixed,
                    MaxRetries = 120,
                    Delay = TimeSpan.FromMilliseconds(500),
                    MaxDelay = TimeSpan.FromMilliseconds(5000)
                }
            });
            using Stream blobStream = await blob.OpenWriteAsync(true, null, cancellationToken);

            await sourceStream.CopyToAsync(blobStream, cancellationToken);
        }

Expected behavior

I would expect to have 120 retries in the log and to have 500 ms between them.

Actual behavior

It seems to have only 4 retries with a very short period of time.

Reproduction Steps

I created a URL with Sas token and I’m trying to upload it. (Not the same service as the one creating it)

Environment

Dotnet 6.0, in a container

Is there any way to just override the stream return to retry on this specific error?

I would also recommend waiting for the policy sas token to become valid before attempting to upload, instead of retrying until the policy becomes valid. Just to clarifiy, it’s a Stored Access Policy ?

How do you detect that the policy is now valid without blindly waiting 30 seconds?
