| AppendFromByteArrayAsync(Byte[], Int32, Int32, AccessCondition, BlobRequestOptions, OperationContext, IProgress<StorageProgress>, CancellationToken) |
Initiates an asynchronous operation to upload the contents of a byte array to an append blob.This API should be used strictly in a single writer scenario because the API internally uses the append-offset conditional header to avoid duplicate blocks which does not work in a multiple writer scenario. |
