<asp:ScriptManager ID="ScriptManager1" runat="server">
    <Services>
    <asp:ServiceReference Path = "~/WebService.asmx" />
    </Services>
    </asp:ScriptManager>

Typically some additional logic required for a web application may be placed in a webservice. In C# web applications we create objects of type service client and invoke the service methods through that object. In AJAX the role is similar except that the service is referenced through the ServiceReference directive. For example you may include an autocompletion logic in a Web service named Auto. Then you will reference that service in your scriptmanager and the logic of autocompletion can then be used on the ASP.NET AJAX page.
