Mike 1 thing is development another one is Deployment.
in development you can reference the project, or the dll from the directory where it is build, now to deploy what you will need to do is on your setup program add the assembly to the Global Assembly Cache Special Folder, you can also go to the properties page when the assembly is selected and set the ShareLegacyFile to true what this will do is add a count to the assembly, this is usually use when multiple applications install the same asssembly as looks like it will be your case.
Build the install and you should be ready to rock.
