Building Bots with Microsoft Bot Framework

Overview of this book

Bots help users to use the language as a UI and interact with the applications from any platform. This book teaches you how to develop real-world bots using Microsoft Bot Framework. The book starts with setting up the Microsoft Bot Framework development environment and emulator, and moves on to building the first bot using Connector and Builder SDK. Explore how to register, connect, test, and publish your bot to the Slack, Skype, and Facebook Messenger platforms. Throughout this book, you will build different types of bots from simple to complex, such as a weather bot, a natural speech and intent processing bot, an Interactive Voice Response (IVR) bot for a bank, a facial expression recognition bot, and more from scratch. These bots were designed and developed to teach you concepts such as text detection, implementing LUIS dialogs, Cortana Intelligence Services, third-party authentication, Rich Text format, Bot State Service, and microServices so you can practice working with the standard development tools such as Visual Studio, Bot Emulator, and Azure.

Calling LUIS from the bot

In the previous step, we set up and configured the LUIS app and also trained it. Now, let's see how you can use the LUIS app in a bot application. To incorporate a call to LUIS, we can start by adding the mentioned function. It simply calls LUIS REST API and returns the phrases and intents we set up in LUIS, for example, name, city, company name, and so on.

Return to Visual Studio and open the MessagesController.cs file; under the Post method, update the code to get the LUIS results, as follows:

var luisOutputString = "Intent and Language Understanding Intelligence Service Processing results are \r \n"; 

The following line of code is where we frame a LUIS app REST API URL--if you observe, we are passing the LUIS app ID and LUIS subscription key; this is the URL you copied from the above step, publishing settings of the LUIS app:


var luisRequestURL =
