Navigate Smatigate It dont work!

I just read part3 of Carl Moore's tutorial on .net and couldn't get this chunk to build correctly. anyone know why?
<vbcode>
Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
Navigate("WebForm2.aspx")
End Sub

That was from VS.NET Beta 1 I believe. Just use Response.Redirect ("your url")
