InheritInChildApplications attribute not recognized in web.config location element

Question

I've tried wrapping my

<system.web>

with

<location path="." InheritInChildApplications="false">

like this

<location path="." InheritInChildApplications="false">
<system.web>...</system.web>
</location>

But VS 2010 Web Developer Express keeps saying

The 'InheritInChildApplications' attribute is not allowed

When I run my web app there's an error:

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

Config Error Unrecognized attribute 'InheritInChildApplications'.

My configuration: ASP.NET 4.0 RTM, VS 2010, IIS 7.5

Solution 1

Shouldn't it be a lowercase 'i'?

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

I have been using it successfully on the last 4 or 5 projects I have worked on. My spec is similar to yours. I'm still using .NET 4 RC. I also include the system.webServer settings within location.

Good luck,

Rich

Solution 2

It could be because you don't have a namespace specified on the root node? eg

You need

<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">

not

<configuration>

Solution 3

I think the issue here is that inheritInChildApplications is not a valid attribute of the location node in .net 4.0.

The reason the above fix works is because you are specifically targeting the .net 2.0 configuration schema

<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">

.net 4.0 privdes a different way of dealing with config inheritance.

See http://msdn.microsoft.com/en-us/library/b6x6shw7.aspx and http://msdn.microsoft.com/en-us/library/ms178692.aspx for more details.

Solution 4

I use clear quite often to achieve this:

<configuration>
   <system.web>
  <assemblies>
     <clear>
  <clientTarget>
     <clear>
  <compilation>
     <compilers>
        <clear>
  <httpHandlers>
     <clear>
  <httpModules>
     <clear>
  <serviceDescriptionFormatExtensionTypes>
     <clear>
  <webServices>
     <protocols>
        <clear>
  <soapExtensionTypes>
     <clear>
  <soapExtensionReflectorTypes>
     <clear>
  <soapExtensionImporterTypes>
     <clear>

Did you ever get this to work? I am having the same issue ...

[mare]

nope, I solved my issues in root app but the application in a sub folder never worked.

[mare]

Aaarrrgh! LOL! It's capitalized in MSDN manuals, so I used it as such.

[mare]

Ok, the root website is working now, but the subdirectory (configured as an aplication) still tries to load the contents of my 'namespaces' element.

[kim3er]

That sucks. Let me know if it works. It's worth flagging it on MSDN.

[kim3er]

Have you changed the default application name of the sub app?

[BrunoLM]

There is one problem with it... The web transforms doesn't work with the correct namespace...

[Mark]

Thanks - that also cleaned up a couple of other warning that have been bugging me :)

[dotjoe]

seems .net 4 brought the attribute back?

[bradjive]

This worked for me. Should probably mark this is as the correct answer based on votes.

I tried this and got the error: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. The configuration section 'clear' cannot be read because it is missing a section declaration

[Sparkle]

Just set it above the nodes you wish to clear. <namespaces> <clear /> or <providers> <clear /> or <appSettings> <clear /> etc etc etc

[Sparkle]

I don't like turning off the inheritance altogether so I prefer to use clear where I need to.

[shashwat]

it seems that this schema has problem in loading. When accessing this url directly in browser it is giving error. I think it should an xml file.

[napster]

I don't think it has to refer to an actual file, it just has to match what VS is expecting.

[David Ewen]

If you want to get web transforms working again you also need to define the xmlns in the transform against the configuration node like this <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0" xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transfo‌​rm">

Can I put that around the entire Web.config or just system.web?
