Andria,The connection string in the BO Mapper project is for the business objects and has nothing to do with associating the BO Mapper project to the Visual Studio project. I thought I would just give you step by step and see if you have the same results.
1. Open your tutorial project in Visual Studio
2. Click "StrataFrame" from the menu and the click "Business Object Mapper"
3. You should then see the BO Mapper and the Visual Studio project will have a red X in the treeview. Select the project from the treeview and the click "Configure Project"
4. This will bring up the project selection dialog. To create a new BO Mapper project. click "New."
5. This will bring up the project properties dialog window. In the "Project Name" textbox, type "Tutorial Project". Leave all other fields on the form alone just to make sure the BO Mapper project gets associated with the VS project. You can come back and correct the settings once we verify that it stays connected. You do not have to normally do this, I just want to take everything out of the formula so you can see exactly how the link between the VS project and the BO Mapper project gets established.
6. Click the "OK" button and it will take you back to the BO Mapper window and the red X should be gone.
7. To prove that the configuration will "stick" close the BO Mapper and then come back in. The red X should no longer appear next to the VS project in the treeview. Once you prove this, go back in and set the project settings to your liking by clicking the "Modify Project Properties" link.
Hope this helps.
