I need to know how does svcutil and Visual Studio decide which types can be re-used from referenced assemblies when generating a web service proxy class.

I have an assembly with some types that are declared like this:

namespace MYCOMPANY.BO.Accounting
{
    [Serializable, DataContract]
    public class AccountingPackagePutRequest : Request
    {
        // Fields
        [DataMember]
        public IBooking[] bookings;
        [DataMember]
        public IDocument[] documents;

        // Methods
        public AccountingPackagePutRequest();
    }
}

Now I have an ASP.NET 2.0 web service (ASMX) that is declared like this:

[WebService(Namespace = "uri://my_company.com/XXXImport")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
public class GLSImportAccountingPackagePut : System.Web.Services.WebService
{
    [WebMethod]
    public MYCOMPANY.BO.Accounting.AccountingPackagePutResponse AccountingPackagePut(MYCOMPANY.BO.Accounting.AccountingPackagePutRequest request)
    {
        return new MYCOMPANY.BO.Accounting.AccountingPackagePutResponse();
    }
}

Now I can’t force VS nor svcutil to re-use types from the first assembly on the client when generating a proxy class for this web service.

However if I create a similar web service in WCF and try to generate a proxy class for it types from the first assembly are re-used.

What is the problem here and how can I force VS or svcutil to reuse the types for the ASP.NET 2.0 (ASMX) version of the web service?

    As indicated by kbrimington in “classic” ASP.NET web services there is no way to re-use types as it is possible with WCF.
    I found it stated also here:
    1) http://infiniteimprobability.blogspot.com/2009/02/reuse-type-in-web-service.html
    2) "Reuse existing types" is ignored when adding a service reference
    3) http://mark.mymonster.nl/2007/12/16/reusing-class-library-between-web-service-and-consumer/

    However with a little bit of will this can be done using Schema Importer Extensions.
    See:

    The second link is a google cache of the original post that is no longer available. If you have troubles finding it please let me know (I have a local copy of the page).
