The type or namespace name 'Linq' does not exist in the namespace 'System'

I'm not using Linq here but these are the assemblies in my 3.5 web.config currently:

 

Is therea control panelconfiguration optionthat I mustset in order touse ASP.NET 3.5? I'm getting this error with VS2008 pages?


CS0234: The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?)

I've easily fixed by removing the namespace from my code behind file, as I not using Linq at this point, was just under the impression that 3.5 was installed on the server and I didn't need to do anything to take advantage of it.

thanks,

Yes.. thanks to both replies. I was able to resolve this by creating a new web.config file and updating on the server.
