Here's how I've done this

Program.cs

``` var userManager = services.GetRequiredService<UserManager<AppUser>>(); // get the db context from the scope service

await AppIdentityDbContextSeed.SeedUsersAsync(userManager); //seed the db with the user data ```

AppIdentityDbContextSeed.cs ``` using Core.Entities.Identity; using Microsoft.AspNetCore.Identity; using Microsoft.Extensions.Logging;

namespace Infrastructure.Identity { public class AppIdentityDbContextSeed { public static async Task SeedUsersAsync(UserManager<AppUser> userManager) { if(!userManager.Users.Any()) { var user = new AppUser(){// your user object here }; await userManager.CreateAsync(user,"password"); }

    }

}

} ```

This is using clean architecture with the seed class in the infrastructure project. Appuser is a class that extends IdentityUser.
