Building a AI Chatbot with .NET Core

In today's rapidly evolving digital landscape, providing timely and effective communication is crucial, especially for educational platforms and technical blogs that cater to programmers, students, and IT professionals. Codingvila, a technical blog akin to C# Corner, has established itself as a resource dedicated to assisting tech enthusiasts through articles, tutorials, and community support. To enhance this support system, introducing an AI chatbot can revolutionize the way users interact with the platform. This is where the "Codingvila Chatbot" comes into play, leveraging .NET Core to offer real-time assistance and interactive learning experiences.

Why a Chatbot?

• Instant Support: A chatbot can provide immediate answers to common queries, reducing wait times and improving user satisfaction.
• Scalability: As the user base grows, a chatbot can effortlessly handle multiple queries at once, unlike human counterparts.
• 24/7 Availability: It offers round-the-clock support, crucial for users in different time zones or those working on projects outside typical office hours.
• Personalized Learning: The chatbot can recommend articles and tutorials based on the user's past interactions and preferences.
• Community Engagement: By handling routine questions, the chatbot allows community managers to focus on more complex queries and community-building activities.

Setting Up the Project

Ensure you have the .NET Core SDK installed to begin. Set up a new project using the command line.

dotnet new console -n CodingvilaChatbot
cd CodingvilaChatbot

This creates a basic .NET Core console application which serves as the foundation for our chatbot.

Integrating Microsoft Bot Framework

Utilize Microsoft's Bot Framework for robust chatbot functionalities. Install the necessary packages.

dotnet add package Microsoft.Bot.Builder
dotnet add package Microsoft.Bot.Builder.Integration.AspNet.Core

These tools enable the use of advanced features like dialogues and conversation flows, essential for an interactive chatbot.

Creating the Bot
 

1. Bot Framework Setup

Implement the CodingVilaBot.cs to manage interactions.

using Microsoft.Bot.Builder;
using Microsoft.Bot.Schema;
using System.Threading.Tasks;

public class CodingvilaBot : IBot
{
    public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default)
    {
        if (turnContext.Activity.Type == ActivityTypes.Message)
        {
            string userInput = turnContext.Activity.Text;
            string response = ProcessInput(userInput);
            await turnContext.SendActivityAsync(MessageFactory.Text(response), cancellationToken);
        }
    }

    private string ProcessInput(string input)
    {
        if (input.Contains("hello"))
        {
            return "Hello! Welcome to Codingvila.com, How can I assist you today?";
        }
        else if (input.Contains("help"))
        {
            return "Here are some things you can ask me...";
        }
        else
        {
            return "I'm not sure how to help with that, but I'm learning more every day!";
        }
    }
}

2. Configure Services and Middleware

Adjust Startup.cs to set up services for the bot.

public void ConfigureServices(IServiceCollection services)
{
    services.AddBot<CodingvilaBot>(options =>
    {
        options.State.Add(new ConversationState(new MemoryStorage()));
    });
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseDefaultFiles();
    app.UseStaticFiles();
    app.UseBotFramework();
}

Running the Chatbot

Execute the application

dotnet run

Your chatbot, "Codingvila Chatbot" is now operational locally. It can be extended to support various platforms like Microsoft Teams, Slack, or Facebook Messenger.
