This sample shows how to integrate LUIS to a bot with ASP.Net Core 2.

To try this sample

• Clone the samples repository

git clone https://github.com/Microsoft/botbuilder-samples.git

• [Optional] Update the appsettings.json file under botbuilder-samples/samples/csharp_dotnetcore/12.nlp-with-luis with your botFileSecret. For Azure Bot Service bots, you can find the botFileSecret under application settings.

Prerequisites

Set up LUIS

• Navigate to LUIS portal.

• Click the Sign in button.

• Click on My Apps.

• Click on the Import new app button.

• Click on the Choose File and select LUIS-Reminders.json from the botbuilder-samples/samples/csharp_dotnetcore/12.nlp-with-luis/CognitiveModels folder.

• Update nlp-with-luis.bot file with your AppId, SubscriptionKey, Region and Version. You can find this information under "Manage" tab for your LUIS application at LUIS portal.

  • The AppID can be found in "Application Information"
  • The AuthoringKey can be found in "Keys and Endpoints"
  • The SubscriptionKey can be found in "Keys and Endpoints", under the Key 1 column
  • The region can be found in "Keys and Endpoints", under the Region column

  You will have something similar to this in the services section of your .bot file to run this sample:

  {
      "type":"luis",
      "name":"<some name>",
      "appId":"<an app id>",
      "version":"<a version number>",
      "authoringKey":"<your authoring key>",
      "subscriptionKey":"<your subscription key>",
      "region":"<region>",
      "id":"<some number>"
  },

  The Version is listed on the page. Note: Enter the either authoringKey OR subscriptionKey, not both

• Update nlp-with-luis.bot file with your Authoring Key.
  You can find this under your user settings at luis.ai. Click on your name in the upper right hand corner of the portal, and click on the "Settings" menu option. NOTE: Once you publish your app on LUIS portal for the first time, it takes some time for the endpoint to become available, about 5 minutes of wait should be sufficient.

(Optional) Install LUDown

• (Optional) Install the LUDown here to help describe language understanding components for your bot.

Visual Studio

• Navigate to the samples folder (botbuilder-samples/samples/csharp_dotnetcore/12.nlp-with-luis) and open LuisBot.csproj in Visual Studio
• Run the project (press F5 key)

Visual Studio Code

• Open botbuilder-samples/samples/csharp_dotnetcore/12.nlp-with-luis sample folder
• Bring up a terminal, navigate to botbuilder-samples/samples/csharp_dotnetcore/12.nlp-with-luis folder.
• Type dotnet run.

Testing the bot using Bot Framework Emulator

Microsoft Bot Framework Emulator is a desktop application that allows bot developers to test and debug their bots on localhost or running remotely through a tunnel.

• Install the Bot Framework Emulator from here.

Connect to bot using Bot Framework Emulator V4

• Launch the Bot Framework Emulator
• File -> Open bot and navigate to botbuilder-samples/samples/csharp_dotnetcore/12.nlp-with-luis folder
