Business Object doesn't show up

I create a test Web service like so:

Code:

---

[WebService(Namespace="http://blah.com")]
public class ServiceThingy: System.Web.Services.WebService
{
    [WebMethod]
    public int ReturnFour()
    {
        return 4;
    }
}

---

I create another class other than this, like so:

Code:

---

class BusinessObject
{
    public string doBusiness()
    {
        return "Did business. It was nice.";
    }
}

---

I compile.
I make a new Console application project.
I add a Web Reference to this service asmx in my new console application project.
When I do this:

Code:

---

localhost.

---

I expect the BusinessObject class also to show up, but it doesn't. The main service class shows up, though.

Now, earlier on, only a few days ago, I developed a huge Web Service app with a lot of business objects and all the business object/classes showed up in the client. What's the deal here? Am I missing something obvious?
