Hi.
I find configsource references in the .config-files to be very helpful. However, since these referenced config-files only contain fragments of the entire app.config hierarchy, the IDE complains.
In the app.config file:
<configuration>
<configSections>
<section name="customProfiles" type="SomeConfigClass, SomeAssembly"/>
</configSections>
</configuration>
(snip)
<valveProfiles configSource="Profiles.config" />
in the Profiles.config:
<customProfiles>
<curveProfile number="-1" name="Cusom1" />
</customProfiles>
However, the IDE has associated Profiles.Config file with the DotNetConfig.xsd schema, which expects the "customProfiles" to be declared in the configSections element, which the Profiles.config file does not have.
I am not particularily bothered by this as it basically only affects intellisense and generates misleading tooltips when you point at the blue undersquiggle, but I was surprised that google came up absolutely empty on this. And no, it is not because I included the word "undersquiggle" in my search ;)
