How to create an ASP.NET MVC chat using C# and Microsoft SQL Server?

Question

ASP.NET

You need to create a chat using ASP.NET MVC, C#, Microsoft SQL Server, HTML, CSS. Chat must be free of SignalR or other third-party technologies. And preferably without JavaScript.
Please tell me what to use and in which direction to look? What should be the overall structure? It is desirable to paint on the elements.
I focus on the simplest implementation, only so that it can be called a "chat".
I'm new and just learning all this.
Thank you all in advance.

Answer 1

Without "using SignalR, javascript" the chat won't work, only the forum

Answer 2

Dear Newbie. Whether you like it or not, javascript is not a "third party technology". It's a perfectly standard part of any developer's skill set to use the word "web" in a way that isn't obscene. You have a choice or look for a ready-made solution and solder it to your realities. Or learn javascript.
