Refresh list of classes

I have a project that has all my reverse mapped classes. I then have reference to that project in my web project. I initially ran the reverse mapping tool and created the classes for the tables that I had ready. Now I have added more tables and ran the reverse mapping tool again and my new tables were picked up and classes generated for them. What do I need to do to get my web project to see the newly added classes. All I can see when setting up a datasource are my original classes. 

I found my answer. When you have a seperate class handling the data access part of ORM and you then add or modify the db structure, you have to update the project using reverse mapping and then compile the project.
