實體框架：實體名稱與屬性相同時的元數據？

Question

我有一個EDM實體「擴展」 - 在這個對象內是屬性擴展。我已經把所有其他列連接好了，但是這個連接拒絕連接。我猜，因爲實體和財產共享相同的名稱？ 這裏是我的代碼，擴展不起作用，前綴不工作：

Imports System.Web.DynamicData 
Imports System.ComponentModel.DataAnnotations 
<MetadataType(GetType(ExtensionsMetaData))> _ 
Partial Public Class Extensions 

End Class 
Public Class ExtensionsMetaData 
Private _phones_extensions As Object 
Private _prefix As Object 
Private _did_flag As Object 
Private _len As Object 
Private _sfc_id As Object 
Private _name_display As Object 
Private _floor As Object 
Private _room As Object 
Private _phones_departments As Object 
Private _phones_buildings As Object 
Private _phones_phones As Object 
Private _phones_restriction_classes As Object 
Private _phones_tens As Object 
<DisplayName("Extension")> _ 
Public Property extensions() As Object 
    Get 
     Return _phones_extensions 
    End Get 
    Set(ByVal value As Object) 
     _phones_extensions = value 
    End Set 
End Property 
<DisplayName("Prefix")> _ 
Public Property prefix As Object 
    Get 
     Return _prefix 
    End Get 
    Set(ByVal value As Object) 
     _prefix = value 
    End Set 
End Property 

末級

我如何獲得此代碼工作？我已經查看了所有通過我的數據模型，它看起來像名稱應該是擴展！

我收到的錯誤是：類型'phoneDBentities.Extensions'的關聯元數據類型包含以下未知屬性或字段：擴展名。請確保這些成員的名稱與主類型的屬性名稱相匹配。

這是EF「約定配置」功能的限制。
