Different User Types in ASP.NET Core 2.1 Using Composition
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Today I explored creating different user types based on inheritance.
How to Define and use Different User Types in ASP.NET Core
After exploring solutions, I have learned that another approach is to use composition instead of inheritance.
The problem is that now when I run the initial migration, the following error is returned:
The child/dependent side could not be determined for the one-to-one relationship between 'Type1.User' and 'AppUser.Type1'. To identify the child/dependent side of the relationship, configure the foreign key property. If these navigations should not be part of the same relationship configure them without specifying the inverse.
Question: How can users of different types be created using the following composition?
AppUser.cs
using Microsoft.AspNetCore.Identity;
namespace MyApp.Models
{
public class AppUser : IdentityUser
{
public string FirstName { get; set; }
public string LastName { get; set; }
public Type1 Type1 { get; set; }
}
}
Type1.cs
namespace MyApp.Models
{
public class Type1
{
public int Type1Id { get; set; }
public string Property1 { get; set; }
public AppUser AppUser { get; set; }
}
}

public string Property1 { get; set; }
public string AppUserId {get;set;}//As foreign Key
public AppUser AppUser { get; set; }
}
Create user with specific Type in Register.cshtml.cs.
var user = new AppUser {
UserName = Input.Email,
Email = Input.Email,
Type1= new Type1{ Property1="Admin"}
};
var result = await _userManager.CreateAsync(user, Input.Password);
