cannot see all public classes within web service namespace

hello all,

i have created a simple web service:

public class ImmediateResponse : System.Web.Services.WebService
{
public ImmediateResponse()
{
}

[WebMethod]
public string getString(string sLang)
{
return "you are speaking " + sLang;
}

public class Inputs
{
public Inputs()
{
}

[WebMethod]
public string getString(string sLang)
{
return "you are speaking " + sLang;
}
}
}

When I add a web reference for this class in another project, I am only
able to create instances of the ImmediateResponse class -> I am unable
to create instances of the Inputs class..

Any ideas ?

Thanks in advance
