Hi jmontano,
There is no front controller in MVC Core.
You need to create a base Controller and inherit base controller in every controller.
public class BaseController : Controller
{
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
}
}
Now inherit each Controller with base Controller.
public class AccountController : BaseController
{
}
For more details refer below link.
