Here is the code we came up with for cloning. This works in Silverlight 2 & 3.

Public Shared Function Clone(Of T)(ByVal source As T) As T
    Dim serializer As New DataContractSerializer(GetType(T))
    Using ms As New MemoryStream
        serializer.WriteObject(ms, source)
        ms.Seek(0, SeekOrigin.Begin)
        Return DirectCast(serializer.ReadObject(ms), T)
    End Using
End Function
