I'm trying to add Forum module from DNN to my Web Site manually , so I add DNN dlls , some controls and Desktop Module forum , then I do :

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Forum.aspx.cs" Inherits="Forum" %>

<%@ Register  TagPrefix = "Nuke" TagName = "Forum" Src = "~/DesktopModules/Forum/Forum_Container.ascx" %>

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">

    <Nuke:Forum ID = "ArtNF" runat="server" ClientIDMode="AutoID" />

</asp:Content>

but it's only a try and Error message here :
