tempdata

I'm putting a value into TempData on first request in an actionfilter. filterContext.Controller.TempData["value"] = true; after that a second request comes in and I check for the value filterContext.Controller.TempData.ContainsKey("value") the value is there. Then a third request comes in and I check for the value again filterContext.Controller.TempData.ContainsKey("value") and the value is still present.

I've been trying to pass data to an action after a redirect by using TempData like so: if (!ModelState.IsValid) { TempData["ErrorMessages"] = ModelState; return RedirectToAction("Product", "ProductDetails", new { code = model.ProductCode }); } but unfortunately it's failing with the following message: ' System.InvalidOperationException The Microsoft.AspNet.Mvc.SessionStateTempDataProvider' cannot serialize an object of type 'ModelStateDictionary' to session state.'
