ConfigurationManager.AppSettings

It's good that I didn't jump into the VS.Net 2005 right away, since there's quite some gotta that people need to jump thru.

For instance, when I used ConfigurationSettings.AppSettings, I got a message saying that the object has been retired. I need to:

- Add reference to the System.Configuration.dll
- Use System.Configuration.ConfigurationManager.AppSettings instead.

Reference:
- ConfigurationManager.AppSettings
- Another reference
