UppercuT comes with ConfigBuilder. What is ConfigBuilder? ConfigBuilder will build a configuration file per environment so you no longer have to maintain a bunch of configuration files. In any project you have app.config (or web.config) files. You just create a .template file next to it. The web.config has a file next to it named web.config.template. What do you name the app.config template files? You have to name the file based on what app.config becomes when visual studio builds the application.
