Solution 1

In ASP.NET 3.5 and 4.0 WebExtension namespace (Ajax services) is already enabled by default. This might lead to an error that the entries are duplicated. Just remove/comment the AJAX extension related entries and it should be good.

Refer:
ASP.NET known breaking changes as reported by Microsoft[^]
There is a duplicate 'system.web.extensions/scripting..[^]

UPDATE: Just came across this blog entry, can look at this too: IIS deployment error: There is a duplicate scriptResourceHandler section defined[^]

Thanks...Yes i commented it worked for WCF service. Same Error am getting for a web application after removing when i browse default.aspx is not opening getting

"The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. "

Check the framework for Web project used! If it is still using old one that those configs would be required for it.

Further, 404 for what? Which page or resource requested returned as such?

using the latest framework not the old one. When i browse for Default.aspx am getting 404. Any idea ?>

That is entirely different question and reason. Please close this question accepting answer and create a new one for other issue.
