I was reading about config files, which are stored as xml. They look interesting. I was wondering if anyone used them as a place to store your applications state between executions. It looks simple and I am going to be trying it. It would be better than storing them in the registry...I dislike the registry.

You can also do a bunch of different things with them, like make simple changes to your app without having to re-deploy the whole thing...that is if you create your app the way that is needed.
