MVC 4從控制器添加腳手架視圖拋出錯誤

Question

當我嘗試使用腳手架模板從控制器方法添加視圖時出現錯誤。選擇哪個模板並不重要，我得到一個錯誤。我使用VS2012更新2

控制器方法和模型有：

public ActionResult EditInventoryItem(int id) 
    { 
    InventoryRepository repo = new InventoryRepository(); 
    Inventory inventoryItem = repo.GetSingle(id); 
    return View(inventoryItem); 
    } 

    public class Inventory 
    { 
     public int Id { get; set; } 
     public string Number { get; set; } 
     public string Description { get; set; } 
     public string Category { get; set; } 
     public string Group { get; set; } 
     public string Manufacturer { get; set; } 
     public string ManufacturerModelNumber { get; set; } 
    } 

我沒有線索什麼是錯的事。是的，我引用了錯誤消息中提到的程序集。這些程序集是System.ComponentModel.DataAnnotations，System.core，System.Data.Entity和System.Data.Linq。我只放置四條消息中的一條 - 時間太長。

C:\Program Files (x86)\Microsoft Visual Studio 11.O\Common7JDE\IteniTemplates\CSharp\Web\MVC 4\CodeTemplates\AddView\CSHTML\Details.tt(-1,-1): error: The host threw an exception while trying to resolve the assembly reference System.ComponentModel.DataAnnotations.

更新：我不能在這裏發表圖片，所以鏈接下面的屬性。更改副本本地不會改變行爲。

DataAnnotations properties

Answer 1

我有完全相同的問題，它涉及到Microsoft代碼挖掘擴展0.95。禁用擴展允許腳手架過程順利地工作，沒有任何錯誤。

Answer 2

我會運行它實際上看是怎麼回事，加上我不能告訴如果你列出你的組件或錯誤代碼。但這是我認爲可能是錯誤的。歡迎您嘗試一下，看看。

public class InveentoryController : Controller 
    { 
     InventoryRepository repo = new InventoryRepository(); 

     public ActionResult EditInventoryItem(int id = 0) 
     {   
      Inventory inventoryItem = repo.inventoryItem.Find(id); 
       if (inventoryItem == null) 
      { 
       return HttpNotFound(); 
      } 
      return View(inventoryItem); 
     } 
    }
