I have inherited an application that was built by a development company that has several Master files with RadScriptManagers in them respectively.  The application is using telerik.Web.UI, version 2009.3.1210.20.  The IIS is configured to use ASP.NET 2.0.  I am running everything locally on my computer.  Originally the company gave us a compiled version of the website, which works fine.  However, trying to get the code in VS with no build errors is frustrating.  Here is what happens.  The Source in the aspx file contains <telerik:RadScriptmanager ....></RadScriptManager>.  However, intellisense shows a warning, "Element 'RadScriptManager' is not a known element.  This can occur...."  When I try to build the app I get the following error. "Method 'get_EnbaleCdn' in type 'System.webUI.ScriptManager' from assembly 'System.Web.Extensions, version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.

Only framework 2.0 and 4.0 are installed on my computer.  I installed Telerik 2010 Q1,2,3 on my pc in addition to a 2006 version.  However, the application's version is the 2009 version indicated above. 

Can someone tell me what is causing this error?  I have gone through the threads, but nothing seems to apply to me thus far to my knowledge (I'm relatively new to Telerik this year).  Any ideas?

Here is the Master file (the are several master files and they all have similar markup.

Solution provided by individual on Expert-Exchange.com:  http://dotnetdailyissues.blogspot.com/2010/06/radscriptmanager-strange-error-method.html.  I also had to be sure this was done in the web.config file.

<assemblyBinding appliesTo="v2.0.50727" xmlns="urn:schemas-microsoft-com:asm.v1">

It worked for me.  No more issues and I am now able to run the application successfully.

I know its over 10 years since the last comment on this, but while this solution seemed to work for me, the AJAX requests no longer functioned correctly.

It turned out that by uninstalling ASP.NET 2.0 AJAX Extensions and reinstalling them resolved the Script Manager issue.  A repair didn't work.

In my case the AJAX extensions were installed before Visual Studio and I found if I try to create a new Web Project the AJAX-Enabled Web Application was not available until after a fresh install of the extensions and then my solution had no issues finding the Script Manager.

Hi William,

I just replied to your other forum post about the RadScriptManager. You need to use this declaration with the telerik prefix in front of the RadScriptManager tag:

 

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <Scripts>
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
            </Scripts>
</telerik:RadScriptManager>
