Question

我似乎没有得到它。我只是想从VS2015 Web核心模板创建一些用户（理想情况下来自核心控制台应用程序，但似乎需要更多设置）

所以我从Startup.cs中调用Initialize

UserManager为NULL，因此无效。我错过了什么？

DbInitializer.Initialize（上下文）;

  public static class DbInitializer
{
    public static UserManager<ApplicationUser> UserManager { get; private set; }


    public static async void Initialize(ApplicationDbContext context)
    {
        var user = new ApplicationUser { UserName = "abc@xxx.com" };
        IdentityResult result = await UserManager.CreateAsync(user, "password");


        //var ttime = DateTime.Now;
        //for (int j = 0; j < 100; j++)
        //{
        //    var start = DateTime.Now;

        //    for (int i = 0; i < 100; i++)
        //    {
        //        var email = "user" + ((j * 100) + i) + "@constoso.com";
        //        var user = new ApplicationUser { UserName = "Bob", Email = email };
        //        var result = await UserManager.CreateAsync(user, "ccc");
        //    }
        //}
    }
}

如果你坚持从Startup中调用它，请传递ServiceProvider并从那个获取Usermanager：

DbInitializer.Initialize(app.ApplicationServices);

public static async void Initialize(IServiceProvider services)
{
    using (var scope = services.GetRequiredService<IServiceScopeFactory>().CreateScope()) {
        var manager = scope.ServiceProvider.GetRequiredService<UserManager<ApplicationUser>>();

        var user = new ApplicationUser { UserName = "abc@xxx.com" };
        var result = await manager.CreateAsync(user, "password");
    }
}
