The DARL Bot

This bot interfaces with the DARL Bot framework to create a bot hosted on Azure. The functionality of the bot is determined by the bot model hosted on and any rulesets (skills) you attach.


  • .NET Core SDK version 2.1

    # determine dotnet version
    dotnet --version

To try this bot

  • Set up the AppSettings.json. Create a free account at and retrieve your API key as described here. You will automatically be given a sample bot model called "thousandquestions.model" which you can insert below.

      "MicrosoftAppId": "The app id or empty for local testing",
      "MicrosoftAppPassword": "The app password or empty for local testing",
      "DarlAPIAddress": "",
      "DarlAPIKey": "The DARL API key for your account",
      "DarlBotModel": "The name of the bot model you are using",
      "initialText":  "Hello from DarlBot"
  • In a terminal, navigate to DarlCoreBot2

    # change into project folder
    cd # DarlCoreBot2
  • Run the bot from a terminal or from Visual Studio, choose option A or B.

    A) From a terminal
