I am trying to create an azure data factory by following this article Create, monitor, and manage Azure data factories using Data Factory .NET SDK
Now I am getting following error:
Copy activity encountered a user error at Sink side: ErrorCode=UserErrorBlobUploadFailed,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=,Source=,''Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Error occurred when trying to upload blob 'https://teststorageaccount.blob.core.windows.net/adftutorial/apifactoryoutput/20140809-00/Data.27643436-2075-4d2f-9ae4-4b8626cc1b69.txt', detailed message: The remote server returned an error: (400) Bad Request.,Source=,''Type=Microsoft.WindowsAzure.Storage.StorageException,Message=The remote server returned an error: (400) Bad Request.,Source=Microsoft.WindowsAzure.Storage,StorageExtendedMessage=Block blobs are not supported.

Can someone point me where I am making mistake?
Note: The blob type is "PageBlob" defined in my azure storage.

Given that your account is
Premium LRS, the behavior is correct as such kind of storage accounts only supportPage Blobs.If your intention is to use a storage account with
Block Blobs, you must create a new storage account where the redundancy type is notPremium LRS.
