How do you get a setting from a configuration file? What do you do when you want to get a setting from a registry, or a database? Everyone faces these problems, and most people come up with their own solution. We used to have a few different standards, but when Microsoft released the Configuration Application Blocks, we have found that working to extend it and use it in all our projects saves us a lot of time! Use a local configuration file for machine and/or user specific settings (such as a connection string), and use a database for any shared values such as Tax Rates.
