XmlInclude or SoapInclude

Question

I am developing a web service that returns arrays of classes that I define in a web service. When I test it, I get: "System.InvalidOperationException: WebSite + HostHeader type was not expected. Use the XmlInclude or SoapInclude attribute to indicate types that are not statically known."

Here is the piece of code:

[WebService(Namespace = "http://WebSiteInfo.Podiumcrm.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class WebSite : System.Web.Services.WebService
{
    public class WebSiteEntry
    {
        public string SiteName = "";
        public string Comment = "";
        public string IISPath = "";
        public int SiteID = 0;
        public ArrayList HostHeaders;

        public WebSiteEntry()
        {
        }
    }
    public class HostHeader
    {
        public string IPAddress = "";
        public int Port = 0;
        public string URL = "";

        public HostHeader()
        {
        }
    }


    [WebMethod(EnableSession = true)]
    [TraceExtension(Filename = @"C:\DotNetLogs\WebSiteServices.log")]
    public WebSiteEntry[] WebSites()
    {...}
}

When I try:

[WebService(Namespace = "http://WebSiteInfo.Podiumcrm.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[XmlInclude(typeof(WebSiteEntry))]
[XmlInclude(typeof(WebSiteProperty))]
[XmlInclude(typeof(HostHeader))]

public class WebSite : System.Web.Services.WebService
{...}

I get: "The type or name of the XmlInclude namespace could not be found (are you missing the using directive or assembly references?)"

Indicates a person who can give me a spell that compiles and executes!

Thanks...
