Asp.net Razor Pages Session

Asp.net Razor Pages Session:

A session is used to store data in browser cached and store in a session variable and access to the whole environment of the application. but razor pages is different seen, it has a page level scope if you want to use session variables globally it is not suitable at this time.so I preferred to you used claim based authentication used cookies is simple and easy to use. so describe below deeply.

USes in Every.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

using Microsoft.AspNetCore.Authorization;

using Microsoft.AspNetCore.Mvc;

using Microsoft.AspNetCore.Mvc.RazorPages;

using Newtonsoft.Json.Linq;

namespace QMPortal.Pages.ServiceProvider

{

[Authorize]

public class AddModel : PageModel

{

public void OnGet()

{

var SessionUser= HttpContext.User.Identity.Name;

ViewData["SessionUser"] = SessionUser;

}

}

}

and if you want to use in Html.cs file like used in view so syntexis

@{

var SessionUser= Context.User.Identity.Name;

var SessionUser = JObject.Parse(SessionUser);

ViewData["SessionUser"] = SessionUser;

}

that is simp-le tutorial to learn using session varible
