why <script> doesn't work in VS.NET 2003?

Code:

---

<script Language="c#" Runat="server">
    void Page_Load()
    {
        Message.Text="hello world";
    }
</script>

---

Code:

---

<asp:Label Runat="server" ID="Message"/>

---

This doesn't work, instead I gotta use the code behind .cs file to define my events... may I be enlightened what actually went wrong?
Thanks...

i think u gotta use Web Matrix in order to use the script tags..

You should use Code Behind in VS.NET 2003.
