Ah okay, I'm pretty sure I was completely wrong with my original
assessment. It's a bug.
Can you replace the head of the foreach with the following?
Asn1Sequence seq =
DerSequence.GetInstance(FromExtensionValue(extVal));
foreach (Asn1Encodable primName in seq)
{
IList list = Platform.CreateArrayList();
GeneralName genName =
GeneralName.GetInstance(primName);
That will do the trick,
Regards,
David
