I'm trying to share information between a windows service app, and a windows forms app that configures the service. I want to store a list of settings, and have to ability to add and remove items from this list.
I decided to use the machine configuration to store this information as it will be shared among multiple apps. I created classes which derive from ConfigurationSection, ConfigurationElement, and ConfigurationElementCollection.
My problem is that I cannot seem to delete any items from my collection. If I call ConfigurationElementCollection.BaseRemove, it seems to mark the item as removed, but the Count property stays the same. If I then call Configuration.Save(ConfigurationSaveMode.Full). It doesn't remove the item from machine.config.
