[IronPython] custom ConfigurationSection in IronPython

[Dino Viehland]

The Item property is the default indexer, so you should be able to access it using foo[index].

As for your other question - Martin looked into this but I didn't see a response from him...  The problem seems to be that we don't define a parameterless constructor that the configuration section can call.  The reason for that is that our objects actually need to receive a DynamicType object which represents the class - without this we wouldn't be able to know your type was MySettings.  Unfortunately I think this might make it impossible for you to define this class in IronPython.  You could define a stub in C# that calls into your Python using the engine APIs but that might be more work than it's worth.

I have another related question.  The "Item" property of System.Configuration.ConfigurationElement (base class for
ConfigurationSection) doesn't seem to be accessible from IronPython.
Is this because its overloaded by parameter type? Is there a way to access it from IronPython?

Thanks
