I am running VS2010 with the bin40 version of the Telerik RadControls with IIS6 - Win2K.  Unfortunately, I cannot get even a simple page to run. 

Has anyone gotten the RadControls to run in VS2010?  If so, have you experienced and solved this problem?

Here's the scenario.

1.)  Create new Telerik project - C# RadControls Web Application

2.)  Project Configuration Wizard - Web Settings
  • Use ScriptManager CDN
  • Use StyleSheetManager CDN
  • Default Controls Scenario generation settings: - Use Ajaxified Templates

3.)  Generated Default.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" />
</head>
<body>
    <form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        <Scripts>
            <%--Needed for JavaScript IntelliSense in VS2010--%>
            <%--For VS2008 replace RadScriptManager with ScriptManager--%>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
        </Scripts>
    </telerik:RadScriptManager>
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    </telerik:RadAjaxManager>
    <div>
    </div>
    </form>
</body>
</html>

4.)  Generated web.config
<?xml version="1.0"?>
<configuration>
    <appSettings>
        <add key="Telerik.ScriptManager.TelerikCdn" value="Enabled"/>
        <add key="Telerik.StyleSheetManager.TelerikCdn" value="Enabled"/>
    </appSettings>
    <system.web>
        <compilation debug="true" targetFramework="4.0"/>
        <pages>
            <controls>
                <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>
            </controls>
        </pages>
        <httpHandlers>
            <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false"/>
            <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false"/>
            <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/>
            <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false"/>
            <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>
        </httpHandlers>
        <httpModules></httpModules>
    </system.web>
    <system.webServer>
        <validation validateIntegratedModeConfiguration="false"/>
        <modules runAllManagedModulesForAllRequests="true"></modules>
        <handlers>
            <remove name="ChartImage_axd"/>
            <add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode"/>
            <remove name="Telerik_Web_UI_SpellCheckHandler_axd"/>
            <add name="Telerik_Web_UI_SpellCheckHandler_axd" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" preCondition="integratedMode"/>
            <remove name="Telerik_Web_UI_DialogHandler_aspx"/>
            <add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode"/>
            <remove name="Telerik_RadUploadProgressHandler_ashx"/>
            <add name="Telerik_RadUploadProgressHandler_ashx" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" preCondition="integratedMode"/>
            <remove name="Telerik_Web_UI_WebResource_axd"/>
            <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode"/>
        </handlers>
    </system.webServer>
</configuration>

5.)  Error message when attempt to run the application:   "JScript runtime error: 'Telerik' is undefined"

6.)  Offending line of code:
//<![CDATA[
Sys.Application.add_init(function() {
    $create(Telerik.Web.UI.RadAjaxManager, {"_updatePanels":"","ajaxSettings":[],"clientEvents":{OnRequestStart:"",OnResponseEnd:""},"defaultLoadingPanelID":"","enableAJAX":true,"enableHistory":false,"links":[],"styles":[],"uniqueID":"RadAjaxManager1","updatePanelsRenderMode":0}, null, null, $get("RadAjaxManager1"));
});
//]]>

7.)  Adding following line to default.aspx does not resolve the problem
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

The only pages that run are from the tutorial, once I run the wizard to update the pages to use .Net 4.0.
