Setting SQL Server CE connection for a dll class library

Question

I can build an app using Windows Forms connecting to a SQL Server CE .sdf file to read and write. Now I need to do the same for a class library .dll project which intended to be a Revit Add-in so I added app.config and Settings.settings as well but in vain!

Any suggestion to properly save the connection string so it would work for multiple desktops?

Thanks in advance!

If you use DataDirectory, you can set the value of that in code:

string path = // folder path to the database file       
AppDomain.CurrentDomain.SetData("DataDirectory", path);
