iis error cant find the solution

Gladis raja

f you see the text "There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined", this error is because you are running a .NET Framework 3.5-based application in .NET Framework 4. If you are running WebMatrix, to resolve this problem, go to the Settings node to set the .NET Framework version to ".NET 2". You can also remove the extra sections from the web.config file.

pls tell the steps for this and get resolve my problem

Check your application Pool (IIS -> Application Pools) if It is running in .net 4.0 then perform the following steps:
1. Cleanup up activity in application level web.config that includes (system.web.extensions)
2. Remove all the section definitions that point to .net 3.5
The reason to remove these sections are these section definitions are already included on root level (machine.config) when you are working with .Net 4.0 framework.
