    When I ran the above script in my Windows VM, it mapped to file share successfully like below:

    enter image description here

    When I checked the same in File Explorer, Z drive is available with test folder in it like below:

    enter image description here

    When I tried to create ABC folder inside test folder, it created successfully like below:

    enter image description here

    I checked the same in Portal where ABC directory is created in file share successfully like below:

    Note that, only UNC paths are supported to create a directory on a remote computer or on a share

    In your case, try changing the path from Z:\\test\\ABC to below:

    Directory.CreateDirectory("\\\\<storageaccountname>.file.core.windows.net\\<storagefilesharename>\\test\\ABC");
