Question

potected override NodeContent GetContent(...    
  BlobClient blobClient = getAZBlobClient(getNodeBlobName(node));
  BlobDownloadInfo download = blobClient.Download();
  return NodeContent.CreateReadOnlyContent(download.Content);
  //return NodeContent.CreateImmediateWriteContent(download.Content.)

Answer 1

mySftpServer.LogWriter = new Rebex.FileLogWriter(@"c:\temp\log.txt", Rebex.LogLevel.Debug);

 public MyAzureProvider(FileSystemProviderSettings fileSystemSettings = null) : base(fileSystemSettings)
{
...
}

var settings = new FileSystemProviderSettings()
                 {
                   LogWriter = new Rebex.FileLogWriter(@"c:\temp\log.txt", Rebex.LogLevel.Debug)
                 };
var myAzureProvider = new MyAzureProvider(settings);

Answer 2

var blobClient = GetBlobClientForNode(node);
  if (contentParameters.AccessType == NodeContentAccess.Read)
  {
    return NodeContent.CreateReadOnlyContent(blobClient.OpenRead());
  }

  var blobClient = GetBlobClientForNode(node);

  if (contentParameters.AccessType == NodeContentAccess.Write)
  {
    var blockBlobClient = GetContainerClientForNode(node.Parent).GetBlockBlobClient(node.Name);
    var blobWriteStream = new BlobWriteStream(blobClient, blockBlobClient, _memoryStreamManager);
    return NodeContent.CreateImmediateWriteContent(blobWriteStream);
  }

Thank you for the support provided above.  

I put some further work into this.  The offending issue in this case is that the returning stream for AZ does not support seek.  To accommodate I utilized code to wrap the stream from the contributors to stackoverflow at this link: https://stackoverflow.com/questions/16497241/how-to-enable-seeking-in-azure-blob-stream

the replacement code is:
 return NodeContent.CreateReadOnlyContent(new SeekableBlobReadStream(blobClient));

Thanks.

This is now working.

Thanks for letting us know. As I wrote in the answer above, we have experimental 'BlogWriteStream' which, as the name suggests, supports 'Write' (upload file) to Azure scenarios.
