c# - “column ”Id“ of relation ”vip_clients“ does not exist” exception -

i trying add data base vipclient.

here chart database:

model:

public class vipclient {     public long id { get; set; }     public virtual client client { get; set; }     public string comment { get; set; }     public datetime creationtime { get; set; } } 

mapping:

public class vipclientmap : imappingentity<vipclient> {     public void map(entitytypebuilder<vipclient> builder)     {         builder.fornpgsqltotable("vip_clients", "clients");         builder.haskey(entity => entity.id);          builder             .hasone(entity => entity.client)             .withmany()             .hasforeignkey("vip_client_id");          builder             .property(entity => entity.comment)             .hascolumnname("vip_client_comment")             .isrequired();          builder             .property(entity => entity.creationtime)             .hascolumnname("creation_time")             .isrequired();     } } 

when add new vipclient db - “column ”id“ of relation ”vip_clients“ not exist” exception

i think problem in mapping
