Get Azure deviceProvisioning Service EnrollmentGroupKeys programatically C#

This should work, but my strings are null

/Get the details for this group
    EnrollmentGroup group = await provisioningClient.GetEnrollmentGroupAsync(groupId);
    logger.LogInformation("Got Enrollment Group: {group}", JsonConvert.SerializeObject(group));
    var attestation  =(SymmetricKeyAttestation)group.Attestation;
    var primaryKey = attestation.PrimaryKey;
    var secondaryKey = attestation.SecondaryKey;
    if(string.IsNullOrEmpty(primaryKey))
        logger.LogWarning("No Primary Key");
    if(string.IsNullOrEmpty(secondaryKey))
        logger.LogWarning("No Secondary Key");    

    logger.LogInformation("Got Keys {pri} and {sec}", primaryKey, secondaryKey);

GetEnrollmentGroupAsync(string) seems to work. It returns an enrollmeent group that has a symmetric key attestation.

Per the docs, there is a getter for those.

The correct Call is GetEnrollmentGroupAttestationAsync

var attestationMechanism = await provisioningClient.GetEnrollmentGroupAttestationAsync(groupId);
    var attestation = (SymmetricKeyAttestation)attestationMechanism.GetAttestation();
    string  primaryKey = attestation.PrimaryKey;
    string secondaryKey = attestation.SecondaryKey;

This assumes it was a SymmetricKeyAttestation. AttestationMethod has a Type property if you need to determine type dynamically.
