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/

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(); } }
