Moving Settings to another config file

asp.netconfigurationsettingsweb-config

Is it possible to move applicationSettings to another config file as it is possible with connectionStrings or appSettings?

When I create Settings for my web application using the designer I get applicationSettings section in my web.config such as:

  <applicationSettings>
    <TestWebApplication.Properties.Settings>
      <setting name="AnotherSetting" serializeAs="String">
        <value>Another setting value</value>
      </setting>
    </TestWebApplication.Properties.Settings>
  </applicationSettings>

I would like to be able to move them to another file like appSettings:

<appSettings configSource="config\appsettings.config"/>

I'm working with a project that has lots of settings accessed through class generated with designer and web.config is extremely hard to maintain between multiple environments. It would be even better if I could force Settings class to use appSettings not applicationSettings.

Is it possible?

Thanks in advance for help.

Waaaay late for this question, but I've just been banging my head against the wall over this one. Turns out you can do this, just not for the entire applicationSettings node, you have to do each child node of the applicationSettings separately. I got the magic info from the bottom of the MSDN SectionInformation.ConfigSource article.

app.config/web.config contents

<applicationSettings>
    <TestWebApplication.Properties.Settings configSource="externalfile.config" />
</applicationSettings>

externalfile.config contents:

<TestWebApplication.Properties.Settings>
    <setting name="AnotherSetting" serializeAs="String">
        <value>Another setting value</value>
    </setting>
</TestWebApplication.Properties.Settings>
