I know this post is a little old, but a have a suggestion that may help some.

I used an Enum to determine what to set in the attribute constructor.

Property declaration :

[DbProperty(initialValue: EInitialValue.DateTime_Now)]
public DateTime CreationDate { get; set; }

Property constructor :

Public Class DbProperty Inherits System.Attribute

    Public Property InitialValue As Object

    Public Sub New(ByVal initialValue As EInitialValue)
       Select Case initialValue
          Case EInitialValue.DateTime_Now
             Me.InitialValue = System.DateTime.Now

          Case EInitialValue.DateTime_Min
             Me.InitialValue = System.DateTime.MinValue

          Case EInitialValue.DateTime_Max
             Me.InitialValue = System.DateTime.MaxValue

       End Select

    End Sub
End Class

Enum :

Public Enum EInitialValue
   DateTime_Now
   DateTime_Min
   DateTime_Max
End Enum
