You need to create a eMail formatted to send to your contact, or anything you want, hope it helps :)

public void SendAppointment()
    {
        try
        {
            MailMessage msg = new MailMessage();
            SmtpClient sc = new SmtpClient("smtp.gmail.com", 587);
            msg.From = new MailAddress("[email protected]", "NEW EVENT");
            sc.Credentials = new NetworkCredential("[email protected]", "password");
            sc.EnableSsl = true;

            msg.To.Add(new MailAddress("[email protected]", "Invited"));
            msg.Subject = "Subject";
            msg.Body = "YOUR CONTENT";

            StringBuilder str = new StringBuilder();
            str.AppendLine("BEGIN:VCALENDAR");
            str.AppendLine("PRODID:-//GeO");
            str.AppendLine("VERSION:2.0");
            str.AppendLine("METHOD:REQUEST");
            str.AppendLine("BEGIN:VEVENT");
            str.AppendLine(string.Format("DTSTART:{0:yyyyMMddTHHmmssZ}", START_DATE));
            str.AppendLine(string.Format("DTSTAMP:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow));
            str.AppendLine(string.Format("DTEND:{0:yyyyMMddTHHmmssZ}", END_DATE));
            str.AppendLine("LOCATION: " + Direccion);
            str.AppendLine(string.Format("UID:{0}", Guid.NewGuid()));
            //str.AppendLine(string.Format("DESCRIPTION:{0}", msg.Body));
            str.AppendLine(string.Format("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:{0}", msg.Body));

            str.AppendLine(string.Format("X-ALT-DESC;FMTTYPE=text/html:{0}", msg.Body));
            str.AppendLine(string.Format("SUMMARY;ENCODING=QUOTED-PRINTABLE:{0}", msg.Subject));
            str.AppendLine(string.Format("ORGANIZER:MAILTO:{0}", msg.From.Address));

            str.AppendLine(string.Format("ATTENDEE;CN=\"{0}\";RSVP=TRUE:mailto:{1}", msg.To[0].DisplayName, msg.To[0].Address));

            str.AppendLine("BEGIN:VALARM");
            str.AppendLine("TRIGGER:-PT15M");
            str.AppendLine("ACTION:DISPLAY");
            str.AppendLine("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Reminder");
            str.AppendLine("END:VALARM");
            str.AppendLine("END:VEVENT");
            str.AppendLine("END:VCALENDAR");
            System.Net.Mime.ContentType type = new System.Net.Mime.ContentType("text/calendar");
            type.Parameters.Add("method", "REQUEST");
            //type.Parameters.Add("method", "PUBLISH");
            type.Parameters.Add("name", "Cita.ics");
            msg.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(str.ToString(), type));
            sc.Send(msg);
        }
        catch (Exception e)
        {
            throw e;
        }
    }
