I am taking a somewhat object oriented approach to an application I am building, and I have been very pleased with the results. However, I am having a problem setting up a class library. The application uses 3 databases and I developed the classes in one of them, but each of the databases will be creating objects from these classes, so I want a central class library. I am finding that even though I have set a reference to the library database, the application does not recognize objects created using these classes. Can anyone help?
