start first conversation with Microsoft bot in Dialogs

Hi,

I have the following code in conversationupdate:

else if (message.Type == ActivityTypes.ConversationUpdate)
{
// Handle conversation state changes, like members being added and removed
// Use Activity.MembersAdded and Activity.MembersRemoved and Activity.Action for info
// Not available in all channels
private IDialog MakeLuisDialog()
{
return Chain.From(() => new LUISDialog(Balnc.BuildForm));
//throw new NotImplementedException();
}
}

and the form as:

I want when my conversation opens, bot will provide me options in dialog wo select.

some demo/code suggestions will be useful.
