Put the connection string in the config file, that way it can be updated without needing a recompile. The easiest way to do that is to open the Properties folder in the Solution Explorer and then doubleclick on the Settings.settings file, then you get a easy to use interface to create a config file value that you can later reference in your code without needing to write any code for reading the config file.
