following the wealth of information found here how can we get an external .config to work? I've tried the same setup I would use for an external appSettings file, but it is unable to find the file for my custom section.
<configSections>
...
<section name="CustomSettings" type="Fully.Qualified.TypeName.CustomSettings, AssemblyName" />
</configSections>
<!-- this works -->
<CustomSettings attrib1="val1" attrib2="val2" .../>
however...
<!--this does not work-->
<CustomSettings configSource="someExternalFile.config"/>
where someExternalFile.config would contain
<CustomSettings attrib1="val1" attrib2="val2" .../>
any ideas?
