[c#] ‘AuthController’를 활성화하는 동안 ‘Microsoft.AspNetCore.Identity.UserManager’유형에 대한 서비스를 확인할 수 없습니다.

로그인 컨트롤러에서이 오류가 발생합니다.

InvalidOperationException : ‘Automobile.Server.Controllers.AuthController’활성화를 시도하는 동안 ‘Microsoft.AspNetCore.Identity.UserManager`1 [Automobile.Models.Account]’유형에 대한 서비스를 확인할 수 없습니다.

다음은 인증 컨트롤러 생성자입니다.

private SignInManager<Automobile.Models.Account> _signManager;
    private UserManager<Automobile.Models.Account> _userManager;

    public AuthController(UserManager<Models.Account> userManager,
                          SignInManager<Automobile.Models.Account> signManager)
    {
        this._userManager = userManager;
        this._signManager = signManager;
    }

다음은 startup.cs의 ConfigureServices입니다.

public void ConfigureServices(IServiceCollection services)
    {
        // Add framework services.
        services.AddApplicationInsightsTelemetry(Configuration);
        services.Configure<AppConfig>(Configuration.GetSection("AppSettings"));

        //var provider = HttpContext.ApplicationServices;
        //var someService = provider.GetService(typeof(ISomeService));


        services.AddDbContext<Providers.Database.EFProvider.DataContext>(options => options
            .UseSqlServer(Configuration.GetConnectionString("DefaultConnection"),
                 b => b.MigrationsAssembly("Automobile.Server")
            ));


        services.AddIdentity<IdentityUser, IdentityRole>(options =>
        {
            options.User.RequireUniqueEmail = false;
        })
        .AddEntityFrameworkStores<Providers.Database.EFProvider.DataContext>()
        .AddDefaultTokenProviders();
        //services.AddScoped<SignInManager<Automobile.Models.Account>, SignInManager<Automobile.Models.Account>>();
        //services.AddScoped<UserManager<Automobile.Models.Account>, UserManager<Automobile.Models.Account>>();

        services.AddMvc();
        App.Service = services.BuildServiceProvider();

        // Adds a default in-memory implementation of IDistributedCache.
        services.AddDistributedMemoryCache();

        services.AddSession(options =>
        {
            // Set a short timeout for easy testing.
            options.IdleTimeout = TimeSpan.FromSeconds(10);
            options.CookieHttpOnly = true;
        });
