How to maintain state in asp.net core
ASP. NET Core applications are inherently stateless, meaning information isn't automatically carried over between requests.

It uses a server-side store and a cookie on the client to identify the session. Setup: Install the Microsoft.AspNetCore.Session package and configure app.UseSession() in your Startup.cs file. Usage: Access the session through HttpContext.Session property in your controllers. Use methods like SetString , GetInt32 to store and retrieve data.
