I broke the code down to a very simple case:

        public void SendEmails(Guid emailPK, string subject, string html, out int errorCode, out string errorMessage)
        {
            errorCode = 0;
            errorMessage = "";
        }

and now my calling code compiles properly:

                int errorCode;
                string errorMessage;
                emailNotifications.SendEmails(emailPK, email.blk_subject, email.blk_html, out errorCode, out errorMessage);

so it looks like the problem is somewhere in the code that I cut out of the SendEmails method.

Do you have any recommended reading on how to handle the throwing of an error?
