Sharp Architecture inheritance problem -

my problem inheritance.

i have actor class

using system.collections.generic; using sharparch.core; using sharparch.core.domainmodel;

namespace proteria.net.common.domain { public class actor : entity { public actor() { init(); }

    private void init()     {         addresses = new list<address>();     }      public virtual account account { get; set; }     public virtual string number { get; set; }     public virtual string telephone { get; set; }     public virtual string fax { get; set; }     public virtual string email { get; set; }     public virtual string idnumber { get; set; }     public virtual countrycode country { get; set; }       public virtual ilist<address> addresses { get; set; }      public virtual void addaddress(address address)     {         address.actor = this;         addresses.add(address);     } } 

}

and 2 derived classes,

using system.collections.generic; using sharparch.core; using sharparch.core.domainmodel;

namespace proteria.net.common.domain { public class company : actor { private string _companyname;

    protected company()     {          init();     }      public company(string companyname)         : this()     {         check.require(!string.isnullorempty(companyname) && companyname.trim() != string.empty,                       "company name must provided");         _companyname = companyname;     }      private void init()     {         employees = new list<employee>();     }      public virtual account account { get; set; }     public virtual string eorinumber { get; set; }      [domainsignature]     public virtual string companyname     {         { return _companyname; }         protected set { _companyname = value; }     }      public virtual companyncts companyncts {get;set;}      public virtual ilist<employee> employees { get; set; }      public virtual void addemployee(employee employee)     {         employee.company = this;         employees.add(employee);     } } 

} and

using sharparch.core; using sharparch.core.domainmodel;

namespace proteria.net.common.domain { public class contact : actor { private string _forename;

    protected contact()     {     }      public contact(string forename)         : this()     {         check.require(!string.isnullorempty(forename) && forename.trim() != string.empty,                       "contact first name must provided");         _forename = forename;     }      public virtual account account { get; set; }       [domainsignature]     public virtual string forename     {         { return _forename; }         protected set { _forename = value; }     }      public virtual string surname { get; set; }     public virtual string mobile { get; set; }  } 

}

when call

actor actor = _actorrepository.get(id);

it works fine. , correct type of actor -> company or contact

the problem when embed actor class class below.

using system; using system.collections.generic; using nhibernate.validator.constraints; using sharparch.core; using sharparch.core.domainmodel;

namespace proteria.net.common.domain { public class article : entity { private string _number;

    public article(string number, account account)         : this()     {         check.require(!string.isnullorempty(number)                       && number.trim() != string.empty,                       "articlenumber must provided");          check.require((account != null), "account must provided");          _account = account;          _number = number;     }      protected article()     {          init();     }       private void init()     {         descriptions = new list<articledescription>();         unitprices = new list<articleprice>();     }      private account _account;     public virtual account account     {         { return _account; }         set { _account = value; }     }      [domainsignature]     [notnull, notempty]     public virtual string number     {         { return _number; }         protected set { _number = value; }     }      public virtual actor sender { get; set; }     public virtual currencycode currencycode { get; set; }     [notnull]     public virtual languagecode languagecode { get; set; }     public virtual articlencts articlencts { get; set; }     public virtual articlede articlede { get; set; }     public virtual articlese articlese { get; set; }     public virtual articleno articleno { get; set; }     public virtual countrycode countrycode { get; set; }     public virtual hscode hscode { get; set; }     public virtual double grossweight { get; set; }     public virtual double netweight { get; set; }     public virtual string exportcode { get; set; }     public virtual string importcode { get; set; }     public virtual string tariccode { get; set; }     public virtual ilist<articledescription> descriptions { get; set; }     public virtual ilist<articleprice> unitprices { get; set; }      public virtual void addarticledescription(articledescription articledescription)     {         descriptions.add(articledescription);     }      public virtual void addarticleprice(articleprice articleprice)     {         unitprices.add(articleprice);     } } 

}

then if call

article article = _articlerepository.get(articleid);

article.sender won't mapped correctly, in base type, not derived type.

i not sure if doing wrong.
