await transferUtility.UploadAsync(new TransferUtilityUploadRequest
{
    BucketName = bucketName,
    Key = blobName,
    InputStream = stream
});
```

itemWrapper.DownloadInfo = new Core.DownloadInfo
{
    Content = await S3StorageLibrary.Utilities.GetContent(transferUtility, bucketName, itemContentBlobName, Key),
    ContentLength = await S3StorageLibrary.Utilities.GetContentLength(S3Client, bucketName, itemContentBlobName, Key)
};
```

Download from S3
```
string itemContentBlobName = Utilities.GetDriveItemContentBlobName(itemBlobName);
Azure.Storage.Blobs.BlobClient itemBlobContentClient =
    GetBlobContainerClient().GetBlobClient(itemContentBlobName);
if (itemBlobContentClient.Exists())
{
    var contentBlobDownload = itemBlobContentClient.Download().Value;
    itemWrapper.DownloadInfo = new Core.DownloadInfo
    {
        Content = contentBlobDownload.Content,
        ContentLength = contentBlobDownload.ContentLength
