If you update you application to .Net Framework4.0, but assign this application to an application pool running under .Net Framework3.5 or previous version, you will encounter this error.

Where are sudo's insults stored? Delete the System.Web.Extensions from your web.config if you don't need it. (it will use the default values from the machine.config) 2. http://forums.asp.net/t/1566645.aspx?Error+500+19+The+configuration+section+system+web+extensions+cannot+be+read+because+it+is+missing+a+section+declaration+ Ivan Dimitrov 16072 posts Registered: 04 Oct 2016 13 Apr 2009 Link to this post Hi Mark, Thank you for getting back to me.
