Hi Nitin,   Try the following code : namespace  WebApplication.Filters {              public   class  SessionTimeoutAttribute: ActionFilterAttribute {                  public   override   void  OnActionExecuting(ActionExecutingContext filterContext) {                     HttpContext ctx = HttpContext.Current;                      if  (HttpContext.Current.Session[ "userId" ] ==  null ) {                         filterContext.Result =  new  RedirectResult( "~/User/Login" );                          return ;                     }                      base .OnActionExecuting(filterContext);                 }             }         }   Reference :   https://www.aspnethostingnews.com/asp-net-core-2-0-hosting-how-to-implement-session-timeout-in-mvc/

This is the MVC code. It's not working in .Net core.

Try This :  using Microsoft.AspNetCore.Mvc; using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc.Filters;     public override void OnActionExecuting(ActionExecutingContext context)
{
if (context.HttpContext.Session.Get("ID") != null)
{
context.Result = new BadRequestObjectResult("Model is null");
return;
}
}   Controller :    [AppSessionFilter]
public class HomeController : Controller
{
// GET: / /
public IActionResult Index()
{
HttpContext.Session.SetString("ID", "Ram");
return View();
}
}
