In your solution explorer under the business project there is a node for references. Right click the references and choose Add references. When the add references form opens click on the Projects tab. You can add a reference to the project instead of a dll file directly. This way the dll is added for you in the bin folder automatically.

Now the reference is added, click on it to highlight it in the solution explorer under references. Now switch to the property window and there is a property for "CopyLocal". Make sure that is set to true. This is more important for straight dll references rather than projects as it will be added everytime you build your project reference anyway. By the way, this bit me in a setup project before because I deliver the setup program and the program crash without some of the dll's getting delivered.

I have no idea what the 1591 error is about as I can't say I have seen that. Did you edit the genereated code somehow?
