Example Of CQS to keep framework entry classes light.

BadController.csx

namespace QS.Admin.Controllers
{
    public class BusinessesController : CommandQueryControllerBase
    {
        private IRepository _repository;
        
        public BusinessController(IRepository repository){
        _repository=repository;
        }
        
        public ActionResult Index()
        {
            try{
                var businesses = _repository.GetAll<Business>().ToList().AsEnumerable());
                var model = businesses.Select(b => b.AsListingViewModel());
                return View(model.ToArray());                
            }
            catch(Exception ex)
            {
                Logging.Exception(ex);
                ViewData["errormessage"]="Unable to retrieve businesses";
            }
            return View(new BusinessListingViewModel[0]);
        }
     }
}

GoodController.csx

namespace QS.Admin.Controllers
{
    public class BusinessesController : CommandQueryControllerBase
    {
        public ActionResult Index()
        {
            var response = Query(new GetBusinessesQuery());
            if (response.Success())
            {
                var model = response.Result.Select(b => b.AsListingViewModel());
                return View(model.ToArray());                
            }
            return View(new BusinessListingViewModel[0]);
        }
     }
}
