.net identityuser problems with entityframework - entity-framework

Question

When we start a normal MVC project it comes with Identity.I have some models like Post.cs and Comment.cs
One to many relationship between post and comment
public class Post
{
public int PostId { get; set; }
public string Baslik { get; set; }
public string Icerik { get; set; }
public virtual ICollection<Comment> Comments { get; set; }
}
public class Comment
{
public int CommentId { get; set; }
public string Icerik { get; set; }
public int PostId {get;set;}
public virtual Post Post { get; set; }
}
IdentityModel.cs We have nothing in here but when i click with ctrl on IdentityUser
public class ApplicationUser : IdentityUser
{
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection")
{
}
}
public class IdentityUser : IUser
{
public IdentityUser();
public IdentityUser(string userName);
public virtual ICollection<IdentityUserClaim> Claims { get; }
public virtual string Id { get; set; }
public virtual ICollection<IdentityUserLogin> Logins { get; }
public virtual string PasswordHash { get; set; }
public virtual ICollection<IdentityUserRole> Roles { get; }
public virtual string SecurityStamp { get; set; }
public virtual string UserName { get; set; }
}
Still weird to me for realationship and i clicked with ctrl on IUser
// Summary:
// Minimal interface for a user with a string user key
public interface IUser
{
// Summary:
// Unique key for the user
//
// Returns:
// The unique key for the user
string Id { get; }
string UserName { get; set; }
}
What am I missing? I just want a relationship user-comment and user-post like between Post and Comment models.
