c# - WCF Rest Code First Can't return a list in a feign key table -

i don't understand wcf rest , code first. if have table patient alone. can have list of patient without problem if have user table , patient table have foreign key on it. can't have list of patient. hope i'm clear enough. find code below service iservice

namespace handyifeservice {     [servicecontract]     public interface ihandyservce       {      [operationcontract]      [webinvoke(method = "get",      requestformat = webmessageformat.json,      responseformat = webmessageformat.json,      bodystyle = webmessagebodystyle.bare,      uritemplate = "test")]      list<patient> getpatientlist();   }  } 

service

public class handyservice : ihandyservce {     public list<patient> getpatientlist()     {         list<patient> listpatients = (from pat in mobile.patient select pat).tolist();         return listpatients;     } } 

code first datamodel

public partial class model1 : dbcontext {     public model1()         : base("name=model1")     {     }      public virtual dbset<patient> patient { get; set; }     public virtual dbset<utilisateur> utilisateur { get; set; }      protected override void onmodelcreating(dbmodelbuilder modelbuilder)     {         modelbuilder.entity<patient>()             .property(e => e.pat_nom)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_prenom)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_adresse)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_ville)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_pays)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_natel)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_teleèhone)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_nommere)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_prenommere)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_nompere)             .isunicode(false);          modelbuilder.entity<patient>()             .property(e => e.pat_prenompere)             .isunicode(false);          modelbuilder.entity<utilisateur>()             .property(e => e.uti_titre)             .isunicode(false);          modelbuilder.entity<utilisateur>()             .property(e => e.uti_nom)             .isunicode(false);          modelbuilder.entity<utilisateur>()             .property(e => e.uti_prenom)             .isunicode(false);          modelbuilder.entity<utilisateur>()             .property(e => e.uti_login)             .isunicode(false);          modelbuilder.entity<utilisateur>()             .property(e => e.uti_password)             .isunicode(false);          modelbuilder.entity<utilisateur>()             .hasmany(e => e.patient)             .withoptional(e => e.utilisateur)             .hasforeignkey(e => e.pat_id_utilisateur);     } } 

patient

user

[table("utilisateur")] public partial class utilisateur {     [system.diagnostics.codeanalysis.suppressmessage("microsoft.usage", "ca2214:donotcalloverridablemethodsinconstructors")]     public utilisateur()     {         patient = new hashset<patient>();     }      [key]     public guid id_utilisateur { get; set; }      [stringlength(15)]     public string uti_titre { get; set; }      [stringlength(100)]     public string uti_nom { get; set; }      [stringlength(100)]     public string uti_prenom { get; set; }      [stringlength(50)]     public string uti_login { get; set; }      [stringlength(200)]     public string uti_password { get; set; }      public guid? uti_id_cabinet { get; set; }      [system.diagnostics.codeanalysis.suppressmessage("microsoft.usage", "ca2227:collectionpropertiesshouldbereadonly")]     public virtual icollection<patient> patient { get; set; } } 

can explain me problem is? in advance best regards

i think can't data of foreign table "patient"

try set reference in class try call "patient" table.

[foreignkey("your foreign key")] public virtual patient patient { get; set; }
