## What it is
Telegram.Bot is the most popular .NET client library for the Telegram Bot API, letting developers build Telegram chatbots in C#. It supports the full Bot API surface including long polling and webhook-based update handling, with extensive documentation and examples.

## Use cases
- build a telegram bot in c#
- send messages from a .net app to telegram
- handle telegram bot updates via webhook in asp.net
- create a telegram chatbot with long polling
- integrate telegram notifications into a dotnet service

## When to choose
- you are building a Telegram bot in .NET/C# and want a mature, well-documented client
- you need full coverage of the latest Telegram Bot API features
- you want examples for console, ASP.NET webhook, or serverless deployments

## When to avoid
- you are not using a .NET language
- you need the full Telegram client API (not just the Bot API) - consider WTelegramClient instead
