I have an application in .net framework 4.0 whose apppool is pointing to 2.0. I tried to change the apppool to 4.0. As soon as I did that, I got an error saying.
There is a duplicate "System.web.extensions/scripting/webservices/JSonSerialization' section defined
The code is compiled in Visual studio 2010 and published on the server.
Any help will be appreciated.

The workaround for the second scenario is to delete or comment out all the system.web.extensions configuration section definitions and configuration section group definitions from the application-level Web.config file. These definitions are usually at
the top of the application-level Web.config file and can be identified by the configSections element and its children.
