c# - WebSecurity.CreateUserAndAccount "Field does not exist" -

i trying extend simple membership include firstname, secondname , email address, getting problems createuserandaccount.

so in registermodel have added following :-

    [display(name = "first name")]     [required(errormessage = "text required")]     public string firstname { get; set; }      [display(name = "second name")]     [required(errormessage = "text required")]     public string secondname { get; set; }      [display(name = "email")]     [required(errormessage = "email required")]     [regularexpression(@"^\w+([-+.]*[\w-]+)*@(\w+([-.]?\w+)){1,}\.\w{2,4}$")]     public string contactemail { get; set; } 

in register.cshtml have added user inputs :-

        <li>             @html.labelfor(m => m.firstname)             @html.textboxfor(m => m.firstname)         </li>         <li>             @html.labelfor(m => m.secondname)             @html.textboxfor(m => m.secondname)         </li>         <li>             @html.labelfor(m => m.contactemail)             @html.textboxfor(m => m.contactemail)         </li> 

and in accountcontroller.cs have following :-

    [httppost]     [allowanonymous]     [validateantiforgerytoken]     public actionresult register(registermodel model)     {         if (modelstate.isvalid)         {             // attempt register user             try             {                 var userinfo =                 new                 {                     firstname = model.firstname,                     secondname = model.secondname,                     contactemail = model.contactemail                 };                  websecurity.createuserandaccount(model.username, model.password, userinfo);                 websecurity.login(model.username, model.password);                 return redirecttoaction("index", "home");             }             catch (membershipcreateuserexception e)             {                 modelstate.addmodelerror("", errorcodetostring(e.statuscode));             }         }          // if got far, failed, redisplay form         return view(model);     } 

the problem when tries

websecurity.createuserandaccount(model.username, model.password, userinfo); 

i getting error following :-

invalid column name 'firstname'.

invalid column name 'secondname'.

invalid column name 'contactemail'.

is because user table not being created fields? if is, how can create fields. have initialize set

        websecurity.initializedatabaseconnection("defaultconnection", "userprofile", "userid", "username", autocreatetables: true); 

any appreciated.

thanks

****update*********************

this userprofile

    public class userprofile : profilebase {     [display(name = "first name")]     public virtual string firstname     {                 {             return (this.getpropertyvalue("firstname").tostring());         }         set         {             this.setpropertyvalue("firstname", value);         }     }      [display(name = "last name")]     public virtual string lastname     {                 {             return (this.getpropertyvalue("lastname").tostring());         }         set         {             this.setpropertyvalue("lastname", value);         }     }      [display(name = "contact email")]     public virtual string contactemail     {                 {             return (this.getpropertyvalue("contactemail").tostring());         }         set         {             this.setpropertyvalue("contactemail", value);         }     }      public static userprofile getprofile(string username)     {         return create(username) userprofile;     } } 

you need add these 3 new fields (firstname, secondname , contactemail) userprofile class inherits dbcontext.

userprofile class defined in accounts model.

[table("userprofile")] public class userprofile {     [key]     [databasegeneratedattribute(databasegeneratedoption.identity)]     public int userid { get; set; }     public string username { get; set; }     public string firstname { get; set; }     public string secondname { get; set; }     public string contactemail { get; set; } } 

make sure delete tables previous tables deleted.
