Calling a Winform hosted WCF service from javascript

Question

I have a Winform hosted WCF service with Ajax Web endpoint.

I also have an ASP.NET project separately, with ScriptManager component on the page.

My question is, should that work if I make service calls to my Winform hosted service from the client side of ASP.NET app using javascript?

My ASP.NET Default page looks like this:

<script type="text/javascript">    
function Button1_onclick() {        
// ????How to call a service method?????    
}
</script>

<asp:ScriptManager ID="ScriptManager1" runat="server">
    <Services>
           <asp:ServiceReference Path="http://localhost:8000/web" />  //My winform hosted service
    </Services>
</asp:ScriptManager>

Or do I have to host my service in IIS to be consumable by AJAX?
