I try to find, but I cant see problem. UPDATE I have specified in application_start in Global.asax ``` protected void Application_Start() { InitializeAutoMapper.Initialize(); } ``` InitializeClass ``` public static class InitializeAutoMapper { public static void Initialize() { CreateModelsToViewModels(); CreateViewModelsToModels(); } private static void CreateModelsToViewModels() { Mapper.CreateMap<Categoies, CategoriesViewModel>(); } private static void CreateViewModelsToModels() { Mapper.CreateMap<CategoriesViewModel, Categoies>() .ForMember(c => c.CategoryPositions, option => option.Ignore()) .ForMember(c => c.Posts, option => option.Ignore()); } } ```
