I found the answer. Sorry for the newbie question. I needed to add a reference to the System.configuration DLL.
>I have been working on Bonnie's data class blogs and have an interesting problem (at least for me). I created a class library for what I call my base data access classes. When I add the database connection screen code from Bonnie's blog cConnection = ConfigurationSettings.AppSettings["ConnectionString"]; I get a warning that the method is obsolete. I changed to the suggested method, cConnection = ConfigurationManager.AppSettings["ConnectionString"]; and get an error ConfigurationManager does not exists. If I put the same code in my web project all is well. My assumption is the class library does not have the web.config file so it does not understand configuration. I do have the same using statements at both places. Is it not possible to create generic data classes this way?
