I needed to redirect to different action method after some work in another action method. I did use RedirectToAction but .NET Core MVC application was only displaying blank. Scenario was: public ActionResult Method1() { .......... .......... var temp = (List<object>)TempData["KeyName"]; } public ActionResult Method2() { .............. List<object> obj = {my list of object}; TempData["keyName"] = obj; RedirectToAction("Method1") } However, application displayed blank page and in URL it was like this "http://localhost/{controller name}/Method2 So, what was the problem? Problem was not in RedirectToAction method. Problem was in the way I assigned data to TempData. To fix the problem, I had to serialize the data before assigning the data to TempData. Solution for the above scenario: public ActionResult Method1() { .......... .......... var temp = JsonConve
