ASP.NET Core MVC. How to implement a dialogue system?

Question

ASP.NET

Good day.
There is an ASP.NET Core MVC application in conjunction with MS SQL Server. The task is to implement a system of dialogues (messages) between users, like in any messenger (Telegram, Skype, VKontakte, etc.). That is, so that the message history is saved in the database and the dialogue can be continued.

Please let me know if anyone faced similar problem and how you solved it. What are the pitfalls, maybe something to read. So far, it comes to mind to write your own infrastructure on top of SignalR.

Answer 1

SignalR is just the chat solution.

Answer 2

Why write something in the Signal?
All logic should be stored in the backend.
The signal, the maximum that can decide is the appearance and how to display (css, html).
