I have a asp.net 3.5 web application and I use a lot of telerik controls in the application.
The web application runs with no problem on asp.net 3.5, but after I converted it to asp.net 4.0, it compiles with no problem, at run-time, I get such errors
1 comes from
<script type="text/javascript">
//<![CDATA[
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');
//]]>
</script>
in the generated html source.
I see that someone else has exactly the same problem at http://forums.asp.net/p/1486516/3512204.aspx#3512204
So, it seems to me that telerik controls are not compatible with asp.net 4.0. Could your team please give me a solution to this problem? Thank you.

I have downloaded the latest telerik ajax controls released april, 2010, and added the Telerik.Web.UI.dll to my solution, but the same ajax errors occur. Could anyone at Telerik let me know how these issues can be fixed? Thank you.

Hi Justin,
Can you please verify that you are using the assemblies from the /bin40 folder of the Q1 2010 SP1 RadControls for ASP.NET AJAX installation as depicted here?
Additionally, we addressed a reported issue concerning the RadAjax compatibility with the ASP.NET AJAX Toolkit for .NET 4.0 in a recent internal build published under the registered users' accounts on our site - you can try it out as well. You may also refer to this sticky forum thread explaining how to use RadScriptManager with the AJAX Toolkit for .NET 4.
Best regards,
Sebastian
the Telerik team
