I'm developing an application which uses some projects.
as you know MVC has built-in security authentication which can be used as code-first,so did I.
In my Main-project I have used IdentityModels.cs to create default tables such as aspnetusers and so on.
in aspnetUsers I want to add a few field such as FirstName,LastName and CityID which has a relationship to City model.
My City Model is in another project which named DomainClasses.
So far I have two projects ,first is Main-Project and the second one is domain classes.
I want to add cityId in my aspnetusers tables which has a relation to City table.
I have added DomainClass reference in Main-Project
these are my codes:
using DomainClasses;
public class ApplicationUser : IdentityUser
{
[MaxLength(25)]
public string FirstName { get; set; }
[MaxLength(50)]
public string LastName { get; set; }
public int PersonalCode { get; set; }
public int CityID { get; set; }
//
public City Cities { get; set; }
...
...
}
so in I must add applicationuser in my city class too.
public class City
{
public int CityID { get; set; }
[MaxLength(30)]
public string CityName { get; set; }
public int CityCode { get; set; }
//I get error in here
public ICollection<ApplicationUser> AppllicationUsers { get; set;}
}
when I want to add Mainproject reference I get circular reference issue.
1. Move your models into a third class assembly that is referenced by both of your projects.
2. Reduce complexity by keeping the Model, View, Controller classes in the same project.

unlike other runtimes, .net projects can not refer to each other. Move the Identity models to the other project.

Hi vahid.ch ,
You can try :
1. Move your models into a third class assembly that is referenced by both of your projects.
2. Reduce complexity by keeping the Model, View, Controller classes in the same project.
