title: C# How to get messages from channel/contact using Telegram API (not Bot API)
body: <p>I found many examples using the bot api, however I need a simple client that implements an event when a message from a contact or group is received, as a user and not a bot (so the Telegram api, and not Bot api). TLSharp library doesn't implement this method.
  What is the best way to achieve it?</p>
