Нет поставщика базы данных Приложение .Net Core Angular

Я пытаюсь создать свою базу данных с помощью .NET Core 2.2 и Angular и столкнулся с этой ошибкой:

No database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider. If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions<TContext> object in its constructor and passes it to the base constructor for DbContext.

У меня есть конструктор по умолчанию в моем классе ApplicationDbContext.

public class ApplicationDbContext : DbContext
{
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> opts) : base()
        {
        }
}

Моя программа cs выглядит нормально для меня:

public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .ConfigureAppConfiguration(SetUpConfiguration)
                .UseStartup<Startup>();

        private static void SetUpConfiguration(WebHostBuilderContext ctx, IConfigurationBuilder builder)
        {
            builder.Sources.Clear();
            builder.AddJsonFile("appsettings.json", false, true)
                    .AddEnvironmentVariables();
        }
    }

И мой запуск регистрирует БД:

private readonly IConfiguration _config;
        public Startup(IConfiguration config)
        {
            _config = config;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
            services.AddDbContext<ApplicationDbContext>(cfg => {
                cfg.UseSqlServer(_config.GetConnectionString("LevanaConnectionString"));
            });

            // In production, the Angular files will be served from this directory
            services.AddSpaStaticFiles(configuration =>
            {
                configuration.RootPath = "ClientApp/dist";
            });
        }
