ConfigurationSection ConfigurationManager.GetSection() always returns null

I am trying to learn how to use the ConfigurationSection class. I used to use the IConfigurationSectionHandler but released that it has been depreciated. So being a good lad I am trying the "correct" way. My problem is that it is always returning null.

I have a console app and a DLL.

class Program
{
    static void Main(string[] args)
    {           
        StandardConfigSectionHandler section = StandardConfigSectionHandler.GetConfiguration();

        string value = section.Value;
    }
}

app config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <configSections>
    <sectionGroup name="ConfigSectionGroup">
      <section name="ConfigSection" type="Controller.StandardConfigSectionHandler, Controller" />
    </sectionGroup>
  </configSections>

  <ConfigSectionGroup>
    <ConfigSection>
      <test value="1" />
    </ConfigSection>
  </ConfigSectionGroup>

</configuration>

section handler in DLL:

namespace Controller
{    
    public class StandardConfigSectionHandler : ConfigurationSection
    {
    private const string ConfigPath = "ConfigSectionGroup/ConfigSection/";

    public static StandardConfigSectionHandler GetConfiguration()
    {
        object section = ConfigurationManager.GetSection(ConfigPath);
        return section as StandardWcfConfigSectionHandler;
    }

    [ConfigurationProperty("value")]
    public string Value
    {
        get { return (string)this["value"]; }
        set { this["value"] = value; }
    }
  }
}

What ever values I try for the "ConfigPath" it will return null, or throw an error saying "test" is an unrecognised element. Values I tried:

• ConfigSectionGroup
• ConfigSectionGroup/
• ConfigSectionGroup/ConfigSection
• ConfigSectionGroup/ConfigSection/
• ConfigSectionGroup/ConfigSection/t
