asp.net mvc 4 scaffolding not working

[Madrid]

I have the following class in a class library\[code\] public class ExpenseDTO{ [Key] public Int32 ExpenseId { get; set; } public Int32 ExpenseTypeId { get; set; } [Display(ResourceType = typeof(Resource), Name = "ExpenseDate")] [Required(ErrorMessageResourceType = typeof(Resource), ErrorMessageResourceName = "ExpenseDataRequired")] [DataType(DataType.Date,ErrorMessageResourceName="InvalidDateFormat" ,ErrorMessageResourceType=typeof(Resource))] [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)] public DateTime ExpenseDate { get; set; } [MaxLength(200, ErrorMessageResourceType = typeof(Resource), ErrorMessageResourceName = "ExpenseNoteMaxLength")] [Display(ResourceType = typeof(Resource), Name = "ExpenseNote")] public String ExpenseNote { get; set; } [Required(ErrorMessageResourceType = typeof(Resource), ErrorMessageResourceName = "ExpenseAmountRequired")] [Display(ResourceType = typeof(Resource), Name = "ExpenseAmount")] public decimal ExpenseAmount { get; set; } public ExpenseDTO() { ExpenseNote = String.Empty; }}\[/code\]i also have an asp.net MVC 4 project that has a class named ExpenseEditView with the following definition\[code\]public class ExpenseEditView{ public ExpenseDTO Expense { get; set; } public IEnumerable<SelectListItem> ExpenseTypeList { get; set; } public ExpenseEditView(ExpenseDTO Expense, IEnumerable<SelectListItem> ExpenseTypeList) { this.Expense = Expense; this.ExpenseTypeList = ExpenseTypeList; }}\[/code\]In the create method of my controller i have the following line: \[code\]public ActionResult Create() { ExpenseEditView ExpenseEdit = new ExpenseEditView(new ExpenseDTO(), GetExpenseTypeList()); return View(ExpenseEdit); }\[/code\]When i tried to use Asp.net mvc Scaffolding template for "create" Action, it created an empty view without generating any code for the properties inside class ExpenseDTO?Can any one please point me to what i am missing so that the template can be generated automatically for ExpenseEditView?
