title: Make .dbml file in a class library use connectionstring from config file without subclassing it
body: <p>I have a class library that is referenced from a web application. The class library defaults to using TestProject.Properties.Settings.Default.NFU_Custom_Website_DataConnectionString1. I would like it to get the connectionstring from ConfigurationManager.ConnectionStrings. </p>
  
  <p>I can't change the .designer.cs file because it will get overwritten. If possible I would like to avoid creating a class which inherits from the .dbml file and setting the connection string in there. My boss recommends creating a web application project and deleting all of the default.aspx etc files from it and using that instead of a class library, is this a viable solution?</p>
  
  <p>Thanks</p>
