I've got aConfiguration object that I can easily read and write settings from and call Save(ConfigurationSaveMode.Minimal, true) on and that typically works just fine.
However, I now have a config file that has a custom sectionGroup defined of type System.Configuration.NameValueSectionHandler (I didn't write that part and I can't change it). Now when I call the Save method, it throws a TypeLoadException
Message:
Type

System.Configuration.ConfigurationSectionGroup.

For reference, the configuration goes like so
<configuration>
<configSections>
... normal sections here that work just fine, followed by ...
<sectionGroup name="threadSettings" type="System.Configuration.NameValueSectionHandler">
<section name="T1" type="System.Configuration.DictionarySectionHandler"/>
<section name="T2" type="System.Configuration.DictionarySectionHandler"/>
<section name="T3" type="System.Configuration.DictionarySectionHandler"/>
</sectionGroup>
</configSections>
<applicationSettings />
<threadSettings>
<T1>
<add key="key-here" value="value-here"/>
</T1>
... T2 and T3 here as well, thats not interesting ...
</threadSettings>
</configuration>
If I remove the actual sections and the definition
for the custom section groups, I am able to read / write settings just fine and even call Save just fine.
Obviously the custom section groups could be setup a little nicer but I can't fix that so I'm wondering: Is it possible to get the Configuration object to save if it has custom sectionGroups of the NameValueSectionHandler type
