The Connector uses an Activity object to pass information back and forth between bot and channel
There is a state per session and a state per user.
The most common type of activity is message

8. Basic Echo bot We are going to first take a look at a message activity
Dialogs are used to model a conversation
The activity will be send to an EchoDialog
Next we are going to take a look at a conversation update activity

9. Luis Bot
LUIS is a Language Understanding Intelligent Service, which offers a  way of adding language understanding to applications
We start with a LUIS App in the LUIS portal
Language understanding is accomplished by Intents

10. Look at the Code Activities are the same as before
We use the message activity
This time the activity will be send to a BasicLuisDialog
In the BasicLuisDialog, we need to add the OrderPizza Intent
The LuisDialog shows what Intent was reached
