ReservationBot
For the development of this bot it is used an abstraction, built on top of the Bot Builder v4. Here you can find more information. Please notice that this is not an official solution, but a personal/experimental solution to prompt user for input (Promptly-dotnet) and manage the conversation flow (topics). See also the documentation about how to manage the conversation flow with dialogs (Coming soon: the same solution using dialogs)
