Bots are becoming increasingly popular, with good reason. Technology has come a very long way; but, there are times when certain technologies seem to reach a point where they cannot go any further. A point where some new “life” is needed—a change, or an improvement. Such is the case with bots.

In the 90s, Web sites became popular. This shifted the software market, or rather, people’s market, to a bright and new shiny platform called the “Web.” Gone were the days where developers developed software solely for the desktop market. The Web has opened up so many possibilities. People could advertise more and reach more people. New businesses started. E-Commerce started.

In the 2000s, a new player arrived: Mobile applications. The coming of smartphones again changed the technology landscape. Developing for the mobile platform has opened up even more possibilities than its predecessor (the Web) could. Everything has become so easy and convenient. Now, basically ten years on since the start of the mobile age, mobile apps have reached their pinnacle. There is not much more you can do, or invent that hasn’t been done or invented on a mobile platform yet.

So, what now?

The answer is: Bots.

Microsoft Bing Bots

A bot is an application that can run automated tasks. These tasks are usually repetitive and bots perform these tasks much faster than humans can. Because of the speed at which bots can perform tasks, they also can be implemented where response speed is faster than how a human can respond and process information.

I have spoken about bots before. You can find those articles here:

Let’s delve a bit deeper into bots today and create a Bing Bot.

Microsoft Bot Framework SDK

The first step in creating a Bing Bot is to download the Microsoft Bot Framework SDK. The Microsoft Bot Framework is a communication service that helps connect your bots with different communication channels, such as SMS and e-mail. The Microsoft Bot Framework includes Bot Builder to give you the tools you need to develop bots.

The Bot Builder SDK is hosted on GitHub. If you are not sure how GitHub works, this article will help in understanding GitHub and Visual Studio better.

Bot Builder includes several samples for you to explore and experiment with in Visual Studio.

Bot Framework Template

Step Two involves obtaining the Bot Framework Visual Studio template. You need to install this template to be able to develop any bot. Download the Bot Application template and install the template by extracting the .zip file into your Visual Studio project templates directory, which is located in the following location:

%USERPROFILE%\Documents\Visual Studio VERSION\Templates\ProjectTemplates\Visual C#\

Now, this is where documentation seems a bit lacking as well as the whole process being cumbersome…

By installing the template, you are by no means ready to start developing your bot. You first have to ensure that you have all the Updated ApiController classes. To update all the necessary namespaces and classes, follow these steps:

  1. Create the Bot Framework project. At this point in time, only C# is supported. Name the project anything descriptive. In this example, I have named my project HTGBing.
  2. Once the project skeleton has been created, you will notice that a lot of the classes will potentially produce errors, as shown in Figure 1.

    Figure 1: Solution Explorer before update

  3. Right-click the project and select Manage NuGet Packages.
  4. In the Browse tab, type “Microsoft.Bot.Builder.”

    NuGet Packages
    Figure 2: NuGet Packages

  5. Locate the Microsoft.Bot.Builder package in the list of search results, and click the Update button for that package.
  6. Preview the changes NuGetwill make.

    Figure 3: Preview NuGet Changes

  7. Follow the prompts to accept the changes and update the package.

Bot Framework Emulator

Step Three involves installing the Bot Framework Emulator. You need to install the Bot Framework Emulator to test your bot properly before publishing it to the Bing portal. Download the Emulator here.

After it has downloaded—it is about 60MB—run the Setup file.

Figure 6 shows the Emulator in action.

Coding Your Microsoft Bing Bot

You will notice how your project is divided and what it consists of in the Solution Explorer. There are three main folders:

  • App_Start
  • Controllers
  • Dialogs

App_Start contains all of the files for your Bing Bot to start. Controllers contain all of the classes that have to interpret and digest the bot’s messages being sent and received. Dialogs contain all the graphical windows of your Bing Bot.

Locate and find the Web.Config file. You will have to enter your Bing Bot’s credentials in here. Obviously, you have not created the Bing Bot on the Bing Bot Portal yet, but it is good to know where to put it, so that when I cover that (a bit later in this article) you will know what I am talking about.

My Web.Config file that includes my Bing Bot’s credentials looks like the following:


<?xml version="1.0" encoding="utf-8"?>
      <add key="BotId" value="HTGBing" />
      <add key="MicrosoftAppId"
           value="d8bd90d3-284f-49c7-a33a-bc047dfe7115" />
      <add key="MicrosoftAppPassword"
           value="E1xdHf9dNLRgwV0n9YOTEXw" />
      <customErrors mode="Off" />
      <compilation debug="true" targetFramework="4.6" />
      <httpRuntime targetFramework="4.6" />
            <clear />
            <add value="default.htm" />

      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="OPTIONSVerbHandler" />
      <remove name="TRACEVerbHandler" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0"
           path="*." verb="*"
           preCondition="integratedMode,runtimeVersionv4.0" />
      <assemblyBinding >
            <assemblyIdentity name="System.Web.Helpers"
                              publicKeyToken="31bf3856ad364e35" />
            <bindingRedirect oldVersion=""
                             newVersion="" />
            <assemblyIdentity name="System.Web.Mvc"
                              publicKeyToken="31bf3856ad364e35" />
            <bindingRedirect oldVersion=""
                             newVersion="" />
            <assemblyIdentity name="System.Web.WebPages"
                              publicKeyToken="31bf3856ad364e35" />
            <bindingRedirect oldVersion=""
                             newVersion="" />
            <assemblyIdentity name="Newtonsoft.Json"
                              culture="neutral" />
            <bindingRedirect oldVersion=""
                             newVersion="" />
            <assemblyIdentity name="System.Net.Http.Primitives"
                              culture="neutral" />
            <bindingRedirect oldVersion=""
                             newVersion="" />
            <assemblyIdentity name="System.Net.Http.Formatting"
                              culture="neutral" />
            <bindingRedirect oldVersion=""
                             newVersion="" />

The BotID setting must be set to the name of your bot. Once you have registered your bot on the Bing Bot Portal, Bing will supply you with the MicrosoftAppId and MicrosoftAppPassword.

Locate and edit the default.htm file:


<!DOCTYPE html>
   <meta charset="utf-8" />
<body style="font-family:'Segoe UI'">
   <p>This is simply an Example Bot.</p>

Default.htm, in this case, provides the user with a simple message. Locate and edit the WebApiConfig.cs file:


using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;

namespace HTGBing
   public static class WebApiConfig
      public static void Register(HttpConfiguration config)
         // JSON settings//
            .NullValueHandling = NullValueHandling.Ignore;
            .ContractResolver = new
            .SerializerSettings.Formatting = Formatting.Indented;
         JsonConvert.DefaultSettings = () => new
            ContractResolver = new
            Formatting = Newtonsoft.Json.Formatting.Indented,
            NullValueHandling = NullValueHandling.Ignore,

         // Web API configuration and services//

         // Web API routes//

            name: "HTGBingMethod",
            routeTemplate: "api/{controller}/HTGBingMethod/{id}",
            defaults: new { id = RouteParameter.Optional }

The WebApiConfig class lets you set up the messaging route. This means that here you should specify how the messages should be sent through to the bot. The end EndPoint would resemble the URL of your bot, along with the Route Template. For example: A Route Template such as the one supplied above might end up looking like this once done:

http://localhost(OR SERVERNAME):3979(OR PORT NUMBER)/api/messages/HTGBingMethod/id

Add the MessagesController class:


using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using System.Web.Http;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Connector;

namespace HTGBing
   public class MessagesController : ApiController
      public async Task<HttpResponseMessage>
         Post([FromBody]Activity activity)
         if (activity.Type == ActivityTypes.Message)
            await Conversation.SendAsync(activity, () =>
               new Dialogs.RootDialog());

         var response = Request.CreateResponse(HttpStatusCode.OK);
         return response;

If a Message (used to communicate between a user and a bot) was sent, the bot needs to display the Root Dialog, which you will add later. There are various types of Messages that you can send to your bot; these include:

  • Text: The actual text being sent
  • Language: The language of the message that gets sent or should be received.
  • Markdown: This includes the basic formatting of the message as well as an indication of the paragraph markdowns, which is obviously the paragraph marker.
  • Attachments: This is the possible attachment to the message. This also includes the type of content being sent to and from the user and the bot.

Add the RootDialog.cs code:


using System;
using System.Threading.Tasks;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Connector;

namespace HTGBing.Dialogs
   public class RootDialog : IDialog<object>
      public Task StartAsync(IDialogContext context)

         return Task.CompletedTask;

      private async Task MessageReceivedAsync(IDialogContext
         context, IAwaitable<object> result)
         var activity = await result as Activity;

         if (activity.Text == "Hannes")
            await context.PostAsync($"Welcome Hannes!");
            await context.PostAsync($"Hello there, Stranger!");


If the user entered “Hannes,” the bot will reply with a welcoming message. Otherwise, the bot will know I am a stranger and act accordingly.
