Web.Config is the recommended place for the connection string to be. Though, I would create a wrapper class and create a method in it that reads and returns ConnectionString from ConfigurationSettings.AppSettings.

>I am not using Mere Mortals.NET (yet!), but I am using the business object in the Hentzenwerke book. Right now, I have the database connection string hard-coded in the BusinessObject base class. Is it a better idea to put this in the web.config file? That seems to be what I am reading so far as best practices. If so, then should I set the connection string from web.config in the BusinessObject constructor method?
