public class ControllerContextFilter : IAsyncActionFilter
{
    public ControllerContextFilter() { }

    public async Task OnActionExecutionAsync(ActionExecutingContext context, ActionExecutionDelegate next)

        // Sample captures response time for controller/actions
        var sw = new Stopwatch();

        sw.Start();
        await next();
        sw.Stop();

        var ad = context.ActionDescriptor as ControllerActionDescriptor;
