c# - AutoMapper binding issues -

i having trouble automapper not mapping , viewmodels correctly. primary model has complex property named contact of type contact, have fields on viewmodel named contact[propertyname] example of contactfirst_name.

which seems correct far documentation examples can find say, trying flatten/unflatten model not working. did find "fix" in thread on stack overflow meant added following line

mapper.initialize(cfg => cfg.recognizeprefixes("contact")); 

to mappings results in successful 2 way binding. seems wrong me , has thinking misunderstanding way default trappings work?

am i?

viewmodel

    public class employeeviewmodel : mvviewmodel {     [display(name = "title")]     public contacttitleviewmodel contacttitle { get; set; }      [display(name = "first name")]     public string contactfirst_name { get; set; }     public string contactmiddle_names { get; set; }     public string contactlast_name { get; set; }     public string contactemail_address { get; set; }     public string position { get; set; }      [tablefields("name")]     public list<employeetrainingviewmodel> training { get; set; } } 

minimal sql models

    public class employee : isqlobject {     public contact contact { get; set; }     public string position { get; set; }     public virtual list<employeetraining> training { get; set; }  }  public class contact : isqlobject     {         public contacttitle title { get; set; }         public string first_name { get; set; }         public string middle_names { get; set; }         public string last_name { get; set; }     }
