Stop inheriting web.config from parent ASP.NET application in IIS 7.5

We have deployed an ASP.NET Website (App 1) in IIS 7.5. Then under that application create another ASP.NET application (App 2). But in App 2, I don't want to inherit the web.config from App 1.

If I try to do the following in App 1's, web.config:

<location path="." inheritInChildApplications="false"> 
    <configSections> 

    <!-- etc -->

    </configSections>
</location>

it reports the error:

Config Error The configuration section 'configSections' cannot be read because it is missing a section declaration

If I try to do:

<remove name = "system.web.extensions" />

it still reports the same error:

asp.net configuration web-config

You can't wrap the whole <configSections> configuration element in a <location path="." inheritInChildApplications="false">. This isn't supported in ASP.NET (yet).

From the documentation:

SectionInformation.InheritInChildApplications Property

The InheritInChildApplications property applies only to location-specific configuration settings.

Also:

Gets or sets a value that indicates whether the settings that are specified in the associated configuration section are inherited by applications that reside in a subdirectory of the relevant application.

<configSection> elements are special and are not configuration settings as such. They are used to define the handlers for configuration settings.

If you need to remove a conflicting configuration <section> from a child application you can do this in the child application's web.config file with the <remove> element:

remove Element for configSections (General Settings Schema)
