When user sen

Answer 1

I believe this could be related to a change that was rolled out a few days ago; where Direct Line will send more ConversationUpdate messages than it used to.

Check the announcement and a related issue (similar to yours, but in node.js).

The first ConversationUpdate is sent when the bot is added to the conversation. After that, each additional ConversationUpdate is sent when a new user joins the conversation.

So, I think the solution here will be to check the members added (activity.MembersAdded)

    else if (message.Type == ActivityTypes.ConversationUpdate)
    {
        if (message.MembersAdded.Any(o => o.Id == message.Recipient.Id))
        {
            // logic
        }
    }

You need to handle that within the main dialog using switch operations based on intent and also adding dialogs for the relevant intent.

There is a difference between introduction and greeting.
