Custom config section is causing Configuration to fail to load

Question

I have added a link to my app.config file to my unit test project and it works, I can see the config values listed. However when I add a custom section as discussed here (How to get the values of a ConfigurationSection of type NameValueSectionHandler) to my XML, ConfigurationManager shows as being in an invalid state in the debugger.

My app.config ends like this:

MSDN says we're not supposed to use the older pre .NET 2 config classes as they are deprecated. So I'm not sure what can be wrong here?

It's a reference to its assembly. I've got it in my project. — Christoph K, Mar 31 '16 at 11:45
Then show us please, how you call the `ConfigurationManager`. And how you read the custom section value. — Christoph K, Mar 31 '16 at 11:47

Aha... I had thought no errors were being logged but found this was being reported which clears it up:

System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Only one element allowed per config file and if present must be the first child of the root element.

I think you might want `type="System.Configuration.NameValueSectionHandler"` not `AppSettingsSection` ? – Crowcoder Mar 31 '16 at 11:52
According to MSDN this is deprecated, though it's confusing because lots of examples use it. – Mr. Boy Mar 31 '16 at 13:42
