    Basic Examples  (2)

    Create a DataConnectionObject to data located in an Azure file:

    Wolfram Language code: DataConnectionObject[ <|"ConnectionName" -> "AzureFiles", "Account" -> "wolframdataconnection", "Container" -> "samples", "Location" -> "coneflower.jpg"|>]

    Retrieve data from an Azure file using Import:

    Wolfram Language code: Import@DataConnectionObject[ <|"ConnectionName" -> "AzureFiles", "Account" -> "wolframdataconnection", "Container" -> "samples", "Location" -> "coneflower.jpg"|>]

    Authentication  (1)

    Give credentials to Azure Files:

    Wolfram Language code: Import@DataConnectionObject[ <|"ConnectionName" -> "AzureFiles", "Account" -> "wolframdataconnection", "Container" -> "samples", "Location" -> "coneflower.jpg"|>, Authentication -> <|"SASToken" -> "token"|>]
