Answer 1

Try inheriting from ActionFilterAttribute And I think the method signature you want is OnActionExecuting(ActionExecutingContext)

For more info, see: http://www.strathweb.com/2015/06/action-filters-service-filters-type-filters-asp-net-5-mvc-6/

Edit: You'll probably also want to add using Microsoft.AspNetCore.Mvc.Filters; at the top if you haven't already.
