entity framework - Automapper maps source to destination but dest values are always null -

i'm new automapper , i'm having problem it. in case automapper used map models(entityframework generated) own viewmodels. happens, sourcemodel it's values mapped destinationmodel dest values null. what's going on values?

now did do: referenced automapper project , bootstrapped mappings.

public static void registerautomappermappings()         {             mapper.initialize(x =>             {                 // add mappingprofiles configured below                 x.addprofile(new registrationviewmodelprofile());             });         }      public static imappingexpression<tsource, tdest> ignoreallunmapped<tsource, tdest>(this imappingexpression<tsource, tdest> expression)     {         expression.forallmembers(opt => opt.ignore());         return expression;     }      public class registrationviewmodelprofile : profile     {         protected override void configure()         {             createmap<registrationviewmodel, contact>().ignoreallunmapped();             createmap<contact, registrationviewmodel>().ignoreallunmapped();              createmap<registrationviewmodel, emailaddress>().ignoreallunmapped();             createmap<emailaddress, registrationviewmodel>().ignoreallunmapped();              createmap<registrationviewmodel, password>().ignoreallunmapped();             createmap<password, registrationviewmodel>().ignoreallunmapped();              //always check if mapping valid             mapper.assertconfigurationisvalid();         }     } 

my viewmodel:

public class registrationviewmodel     {         public httppostedfilebase file { get; set; }         public string emailaddress { get; set; }         public string password { get; set; }         public string contact_givenname { get; set; }         public string contact_surname_prefix { get; set; }         public string contact_surname { get; set; }         public string contact_gender { get; set; }         public string contact_country { get; set; }         public string contact_residence { get; set; }         public nullable<datetime> contact_birth_date{ get; set; }         public datetime create_date { get; set; }         public icollection<int> contact_roles { get; set; }         public string emailaddress_verificationkey { get; set; }     } 

my model:

public partial class contact     {         public contact()         {             this.contact_connection_rel = new hashset<contact_connection_rel>();             this.contact_emailaddress_password_rel = new hashset<contact_emailaddress_password_rel>();             this.contact_emailaddress_rel = new hashset<contact_emailaddress_rel>();             this.contact_service_role_rel = new hashset<contact_service_role_rel>();             this.given_answer = new hashset<given_answer>();             this.given_answer1 = new hashset<given_answer>();         }          public int contact_id { get; set; }         public string contact_initials { get; set; }         public string contact_givenname { get; set; }         public string contact_surname_prefix { get; set; }         public string contact_surname { get; set; }         public string contact_nickname { get; set; }         public string contact_gender { get; set; }         public nullable<system.datetime> contact_birth_date { get; set; }         public string contact_country { get; set; }         public string contact_residence { get; set; }         public string contact_ssn { get; set; }         public nullable<system.datetime> create_date { get; set; }         public nullable<system.datetime> modify_date { get; set; }         public nullable<system.datetime> delete_date { get; set; }          public virtual icollection<contact_connection_rel> contact_connection_rel { get; set; }         public virtual icollection<contact_emailaddress_password_rel> contact_emailaddress_password_rel { get; set; }         public virtual icollection<contact_emailaddress_rel> contact_emailaddress_rel { get; set; }         public virtual icollection<contact_service_role_rel> contact_service_role_rel { get; set; }         public virtual icollection<given_answer> given_answer { get; set; }         public virtual icollection<given_answer> given_answer1 { get; set; }     } 

and test configuration following lines used. vars contain destination objects null:

contact c = new contact(); contact testc = unitofwork.contactrepository.find(82);  var x = mapper.map<contact, registrationviewmodel>(testc); var y = mapper.map(regmodel, c, typeof(registrationviewmodel), typeof(contact)); var b = mapper.dynamicmap<registrationviewmodel, contact>(regmodel); var z = mapper.map<registrationviewmodel, contact>(regmodel, c); var w = mapper.map<registrationviewmodel, contact>(regmodel); 

expression.forallmembers(opt => opt.ignore()); 

you're telling automapper ignore properties, nothing gets mapped.

if want ignore non-matching properties, see this answer 1 way, otherwise you're going have explicitly map each property between objects.
