Integrate Telegram Chat Bot With .NET Core 3

In my previous articles, I briefly explained about front-end frameworks and cross-platform applications with .NET Core 3. Now, I have decided to work on ChatBot and it's very popular presently. That's why I prepared this article on Telegram chatbot with .NET Core 3.

A chatbot is an artificial intelligence software that can replicate a conversation with a user in natural language through a messaging application, websites, ad mobile app. However, from a technical point of view a chatbot acts as a Question Answering System.

There are many points to describe the importance of chatbots but here I have listed only a few of them, such as scaling up operations, handling a lot of customer queries, marketing content through online channels, driving up organization efficeincy, and selling to millennials.

Let's implement a telegram chatbot with .NET Core 3.

First, we have to generate a token with BotFather to handle messages.

Login with telegram and Type @BotFather in search area.

Now, type /newbot in the message. It will ask you to name your bot. In this example. My username is csharpcorner_bot (username must be end with _bot).

Finally, you have your bot token. Now we have to handle messages with .NET Core 3.

Download the latest version of this SDK and install it.

Create a new console application with core 3. The name of my application is csharpcornertelegramchatbot.

You have to add one nuget packge to use inbuit methods. Install this nuget as described here. After, open program.cs file and add the below code in that file.
