Building Bots with Microsoft Bot Framework

Setting up Microsoft Bot Framework Dev Environment

In the past several decades, the corporate, government, and business world has experienced several waves of IT architecture foundations, moving from mainframes, to minicomputers, to distributed PCs, to the Internet, to social media / mobile, and now to the Cloud / Internet of Things (IoT) stack. We call this the sixth wave of corporate IT, and like its predecessors, cloud and IoT technologies are causing significant disruption and displacement, even while they drive new levels of productivity. Each architecture focuses on key business processes and supports killer technology applications to drive new levels of value. Very soon we will be looking at an enormous networked interconnection of everyday machines to one another, as well as to humans.

Lets have a look at the fifth wave of corporate IT:

The machine-to-machine-to-human connectivity will have a profound impact on the consumer and corporate IT experience. As these machines become social and talk to us, we have an enormous opportunity to greatly enhance their value proposition through improved product quality, customer experience, and lowered cost of operations. A heightened consumer expectation for more personal and real-time interactions is driving business to holistically embrace the next wave of technology innovation such as cloud, IoT, and bots to boost business performance. In this age of billions of connected devices, there is a need for such a technology where our apps, such as bots, could talk back. Bots that have specific purposes and talk to any device or any app or to anyone, live in the cloud, we can talk to via any communication channel such as e-mail, text, voice, chat, and many others, can go where no apps have gone before when it comes to the machine-to-machine-to-human connectivity. In order to make this happen, we will need a whole new platform, a platform for conversations.

Conversation as a Service (CaaS)

Messaging apps in general are becoming a second home screen for many people, acting as their entry point to the Internet; where the "youngins" are, the brands will follow. Companies are coming up with messaging apps as bots and apps that offer everything from customer service to online shopping and banking.

Conversations are shaping up to be the next major human-computer interface. Thanks to advances in natural language processing and machine learning, the technology is finally getting faster and accurate enough to be viable. Imagine a platform where language is the new UI layer. When we talk about conversation as a platform, there are three parts:

  • There are people talking to people. The Skype translator is an example where people can communicate across languages.
  • Then, there is the opportunity to enhance a conversation by the ability to be present and interact remotely.
  • Then, there are personal assistants and the bots.

The following screenshot shows the Conversation as a Service:

Think of bots as the new mechanism that you can converse with. Instead of looking through multiple mobile apps or pages of websites, you can call on any application as a bot within the conversational canvas. Bots are the new apps, and digital assistants are the meta-apps. This way, intelligence is infused into all our interactions.

This leads us to the Microsoft Bot Framework, which is a comprehensive offering from Microsoft to build and deploy high quality bots for your users to interact using Conversation as a Platform (CaaP). This is a framework that lets you build and connect intelligent bots. The idea is that they interact naturally wherever your users are talking, such as Skype, Slack, Facebook Messenger, text/SMS, and others. Basically, with any kind of channel that you use today as a human being to talk to other people, you will be able to use them to talk to bots, all using natural language:

The Microsoft Bot Framework is a Microsoft operated CaaP service and an open source SDK. The Microsoft Bot Framework is one of the many tools that Microsoft is offering for building a complete bot. Other tools include Language Understanding Intelligent Service (LUIS), Speech APIs, Microsoft Azure, Cortana Intelligence Suit, and many more.

Your bot

The Microsoft Bot Builder SDK is one of three main components of the Microsoft Bot Framework. First, you have to build your bot. Your bot lives in the cloud and you host it yourself. You write it just like a web service component using Node.js or C#, like the ASP.NET Web API component. The Microsoft Bot Builder SDK is open source, so it will support more languages and web stacks over time. Your bot will have its own logic, but you also need a conversation logic using dialogs to model a conversation. The Bot Builder SDK gives you facilities for this, and there are many types of dialogs that are included, from simple yes or no questions, to full LUIS, which is one of the APIs provided by Microsoft Cognitive Services. This is what the architecture of bot looks like:

The Bot Connector

The Bot Connector is hosted and operated by Microsoft. Think of it as a central router between your bots and many channels to communicate with your bots. Apart from routing messages, it manages state within the conversation. The Bot Connector is an easy way to create a single backend and then publish it to a bunch of different platforms called channels.

The following screenshot illustrates the Bot Connector:

The Bot Directory

The Bot Directory is where the user will be able to find bots. It's like an App Store for mobile apps. The Bot Directory is a public directory of all the reviewed bots registered through the developer portal. Users will be able to discover, try, and add bots to their favorite conversation experiences from the Bot Directory. Anyone can access it and can submit bots to the directory.

As you begin your development with the Microsoft Bot Framework, you might be wondering how best to get started. Bots can be built in C#; however, Microsoft's Bot Framework can also be used to build bots using Node.js. For developing any bots, we need to first set up the development environment and have the right tools installed for successfully developing and deploying a bot. Let's see how we can set up a development environment using Visual Studio.

Setting up the development environment

In this section, we will see how to set up the development environment but, before that, let's check out the prerequisites needed for setting it up.

Prerequisites

To use the Microsoft Bot Framework Connector, you must have the following:

  • A Microsoft account (Hotmail, Live, or Outlook) to log into the Bot Framework developer portal, which you will use to register your bot.
  • An Azure subscription (free trial at https://azure.microsoft.com/en-us/). This Azure subscription is essential for having an Azure-accessible REST endpoint exposing a callback for the Connector service.
  • Developer accounts on one or more communication service (such as Skype, Slack, or Facebook) where your bot will communicate.

In addition, you may wish to have an Azure Application Insights account so that you can capture telemetry from your bot. There are additionally different ways to go about building a bot: from scratch, coded directly to the Bot Connector REST API, the Bot Builder SDK's for Node.js and .NET, and the Bot Connector .NET template, which is what this quick start guide demonstrates.

Setting up the Bot Framework Connector SDK .NET

This is a step-by-step guide to setting up the development environment to develop a bot in C# using the Bot Framework Connector SDK .NET template:

  1. Install the prerequisite software:
    1. You can download the community version of Visual Studio 2015 (latest update) for free at www.visualstudio.com.
    2. Update all VS extensions to their latest versions by navigating to Tools | Extensions and Updates | Updates.
  2. Download and install the Bot Application template:
    1. Download the file from the direct download link, http://aka.ms/bf-bc-vstemplate.
    2. Save the ZIP file to your Visual Studio 2015 templates directory, which is traditionally in %USERPROFILE%DocumentsVisual Studio 2015TemplatesProjectTemplatesVisual C#.
  3. Open Visual Studio.
  1. Create a new C# project using the new Bot Application template:
  1. The template is a fully functional Echo Bot that takes the user's text utterance as input and returns it as output. In order to run, however, the following has to take place:
    1. The bot has to be registered with the Bot Connector.
    2. The AppId and AppPassword from the Bot Framework registration page have to be recorded in the project's web.config.
    3. The project needs to be published to the web.
    4. Use the Bot Framework emulator to test your bot application.

The Bot Framework provides a channel emulator that lets you test calls to your bot as if they were being called by the Bot Framework cloud service. To install the Bot Framework emulator, download it from https://emulator.botframework.com/.

Once installed, you're ready to test, by starting your bot in Visual Studio using a browser as the application host:

This book does not provide any depth on the topic. The author simply walks you through step-by-step instructions on how to create a specific application using the bot framework. The author apparently coded a few small bot applications, then attempts to walk the reader through setting up these applications by copying the authors code (which is not complete or error free) but does not explain what the app being built consists of, or why certain bot framework components are being used. I also purchased the Kindle format, which did an awful job at displaying the text and images. This book truly lacks in any substance about the topic for the reader. Search the internet and you will find much more compelling and informative information.

I bought this book right when it was released. Already out of date. For example, LUIS website is completely changed from the book. Would recommend you don't waste your money.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
