I started a new ASP .NET website in VS 2010 and added a RadScriptManager to default.aspx. I set the validate option on the httphandler add to true and get this error.
Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: Could not load type 'Telerik.Web.UI.WebResource'.

If I change validate to false, I get AJAX errors (sys is undefined etc.).
If I change my target .NET framework to 4.0 the problem goes away. However, I am not prepared to migrate to .NET 4.0 right now. Can anyone help me figure out what is amiss?
I have reinstalled the 3.5 framework as well as the RadControls for AJAX (Q1 2010). I have also tried (Q2 2010) with the same results.
Here is the web.config file if it helps:
