语句错误求助

下面的语句是我从C#转换过来的，提示 INotifyPropertyChanged 错误，“类只能从其他类继承”
---------------------------------------------------------
Public Class data
Inherits INotifyPropertyChanged

Dim _name As String
Public Property Id As Integer
Public Property Name As String

Get
Return _name
End Get
Set(ByVal value As String)
_name = value
OnPropertyChanged("Name")
End Set
End Property

Public Property Age As Integer

Protected Friend Overridable Sub OnPropertyChanged(ByVal propertyName As String)
RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs(propertyName))
End Sub

Public Event PropertyChanged As PropertyChangedEventHandler
End Class
----------------------------------
请问这里的 INotifyPropertyChanged应该怎么写？谢谢！
