Sorry, but your question is not clear. Have you defined key on database level or not? How did you create class - using Code First?

I think what you are asking is that you need to specify the Key attribute on your ID property as EF is looking for it to be named Id instead of ID

VB.NET

Public Class MenuSidebar
    <key>
    Public Property ID() As Integer
    Public Property MenuCode() As String
    Public Property MenuDescription() As String
    Public Property Method() As String
    Public Property Controller() As String
    Public Property MenuInduk() As Integer
    Public Property CreatedTime() As Date
    Public Property CreatedBy() As String
    Public Property LastModifiedTime() As Date
    Public Property LastModifiedBy() As String
End Class</key>
