App.Config Problem VS2005 RC1

Hi
in the msdn i found thishttp://msdn2.microsoft.com/en-us/library/ms134757
that i can give a section a source. In the help i found this
<pages configSource="pages.config"/>
But i doesn#t work
so i have tried this

<sectionname="Siag.TestProject.TestService.BusinessLogic.Agents.Properties.Settings"type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"allowExeDefinition="MachineToLocalUser"requirePermission="false"configSource="filepath and Name"/>

but the compiler it gives me the following warning:
Warning 2 The 'configSource' attribute is not declared

and i doesn't work?! ...
some idea
thx

the docs on http://msdn2.microsoft.com/en-us/library/ms228245(en-US,VS.80).aspx indicate valid attributes are allowDefinition,
allowExeDefinition, allowLocation, name, restartOnExternalChanges, type
