-

i'm trying pass dto 1 navidation property ienumerable<> inside of it, when pass object without child lists works well, but, when i'm passing objects childs , grandchilds wcf services not respond , gives me no error. have make work type of object specificly?

here's data contract

    [servicecontract]         public interface iprodutoservice         {             [operationcontract]             categoriaresponse getcategoria(categoriarequest request);              [operationcontract]             produtoresponse getproduto(produtorequest request);              [operationcontract]             categoriaresponse managecategoria(categoriarequest request);              [operationcontract]             produtoresponse manageproduto(produtorequest request);         }   //and dto class   public class produtodto     {         #region primitive properties         [datamember]         public int32 codigo { get; set; }          [datamember]         public int32 codigocategoria { get; set; }          [datamember]         public string descricao { get; set; }          [datamember]         public decimal? preco { get; set; }         #endregion           #region navigation properties         [datamember]         public categoriadto categoria { get; set; }          [datamember]         public vendadto[] vendas { get; set; }         #endregion     }

// , service configuration looks this:

<services>   <service behaviorconfiguration="behavioraction" name="uniarchitecture.produtoservice.serviceimplementations.produtoservice">     <endpoint binding="wshttpbinding" bindingconfiguration="bindingaction" contract="uniarchitecture.produtoservice.servicecontracts.iprodutoservice">       <identity>         <dns value="localhost"/>       </identity>     </endpoint>     <endpoint address="mex" binding="mexhttpbinding" contract="imetadataexchange" />   </service> </services>  <behaviors>   <servicebehaviors>     <behavior name="behavioraction">       <servicemetadata httpgetenabled="true" />       <servicedebug includeexceptiondetailinfaults="true"/>     </behavior>   </servicebehaviors> </behaviors>   <bindings>   <wshttpbinding>     <binding name="bindingaction" transactionflow="false" receivetimeout="00:30:00" >       <reliablesession enabled="true"/>     </binding>   </wshttpbinding> </bindings>

it child objects not marked serializable.

it looks if missing datacontract attribute.

from comments below looks have objects not serializable. go through objects use , mark them th serializable or data contract attribute.
