I got the same message twice

Question

I used this code to send a different message if a new user start conversation :

IConversationUpdateActivity update = message;
            var client = new Connec         


        

Answer 1

Facebook includes the conversation itself in the list of members:

So you need to change the if statement to this:

if (newMember.Id != message.Recipient.Id && newMember.Id != message.Conversation.Id)
{ 
   // send welcome message

Answer 2

I'm looking into the facebook Name part... You should be able to just plug in this code:

            else if (message.Type == ActivityTypes.ConversationUpdate)
        {
            IConversationUpdateActivity iConversationUpdated = message as IConversationUpdateActivity;
            if (iConversationUpdated != null)
            {
                ConnectorClient connector = new ConnectorClient(new System.Uri(message.ServiceUrl));

                foreach (var member in iConversationUpdated.MembersAdded ?? System.Array.Empty<ChannelAccount>())
                {
                    // if the bot is added, then
                    if (member.Id == iConversationUpdated.Recipient.Id)
                    {

                        var reply = ((Activity)iConversationUpdated).CreateReply($"Hi Friend I'm Botty McBotface");
                        connector.Conversations.ReplyToActivityAsync(reply);
                    }
                }
            }
        }
