Custom ConfigurationSection to external .config

Question

I know there is an easy way to move any "standard" config section to external file i.e.

<appSettings file="myFile.config">

but what about a custom ConfigurationSection?

<configSections>
    <section name="someName" type="Namespace.SomeNameConfiguration" requirePermission="false" />
</configSections>

....

<someName>
  < bla bla bla ......
</someName>

Is there any similar way?

Answer 1

You can use

<somename configSource="myfile.config"/>

However unlike appSettings file=..., you must put the entire section in the external file: there is no merging.
