My fix was extracting it and putting a try catch around the dictionary.Add(key, value) in the method VCardUtil.GetAdditionalKeyMembers
Its everything else but beautiful but it makes it work

I use Nuget, and I get: System.ArgumentException: An item with the same key has already been added.

Which is the key ?

IEnumerable vcards = MixERP.Net.VCards.Deserializer.Deserialize(vcfMovil);

        string contents = File.ReadAllText(vcfMovil, Encoding.UTF8);
        IEnumerable<VCard> vcards2 = MixERP.Net.VCards.Deserializer.GetVCards(contents);

        foreach (var vcard in vcards2)
        {
            Console.WriteLine(vcard.FirstName + " \t " + vcard.MiddleName + " " + vcard.LastName);
            Console.WriteLine(vcard.FormattedName);
        }
