为了使用数据库，我使用 ORM Entity Framework Core。启动应用程序后，对数据库的所有请求都会记录在控制台中。我没有安装日志记录。如何禁用它？

程序.cs：

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddHangfire(x => x.UseSqlServerStorage(builder.Configuration.GetConnectionString("DefaultConnection")));
builder.Services.AddHangfireServer(opt =>
{
    opt.StopTimeout = TimeSpan.FromMinutes(5);
});
builder.Services.AddControllers();
builder.Services.AddSwaggerGen();
builder.Services.AddAutoMapper(typeof(AutoMapperConf));

builder.Services.AddCors(o => o.AddDefaultPolicy(builder =>
{
    builder
    .WithOrigins("http://localhost:80")
    .AllowCredentials()
    .AllowAnyHeader()
    .AllowAnyMethod();
}));

// DB Services
var connectionString = builder.Configuration.GetConnectionString("DefaultConnection");

builder.Services.AddDbContext<AMContext>(options => options.UseSqlServer(connectionString), ServiceLifetime.Transient);
builder.Services.AddDbContext<AMIdentityContext>(options => options.UseSqlServer(connectionString), ServiceLifetime.Transient);

builder.Services.ConfigureApplicationCookie(opt =>
{
    opt.LoginPath = "/auth/login";
    opt.LogoutPath = "/auth/logut";
    opt.AccessDeniedPath = "/";
    opt.ExpireTimeSpan = TimeSpan.FromDays(180);
});

builder.Services.AddIdentity<DBUser, IdentityRole>(config =>
{
    config.Password.RequireNonAlphanumeric = false;
    config.Password.RequiredLength = 1;
    config.Password.RequireUppercase = false;
    config.Password.RequireDigit = false;
    config.Password.RequireLowercase = false;
})
    .AddEntityFrameworkStores<AMIdentityContext>()
    .AddDefaultTokenProviders();

builder.Services.AddSpaStaticFiles(configuration =>
{
    configuration.RootPath = "wwwroot";
});
var app = builder.Build();

app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseCors();
app.UseDefaultFiles();
app.UseStaticFiles();
app.UseHangfireDashboard("/hangfire", new DashboardOptions
{
    Authorization = new[] { new HangfireAuthFilter() }
});

app.MapControllers();
app.UseEndpoints(endpoints =>
{
    endpoints.MapDefaultControllerRoute();
});

app.UseSpa(spa =>
{
    spa.Options.SourcePath = "ClientApp";
    if (app.Environment.IsDevelopment())
    {
        spa.UseAngularCliServer(npmScript: "start");
        spa.UseProxyToSpaDevelopmentServer("http://localhost:4200");
    }
});


RecurringJob.AddOrUpdate<HangFireTaskManager>("TaskParser", (method) => method.TaskParser(), "*/1 * * * * *");
RecurringJob.AddOrUpdate<HangFireTaskManager>("PostParser", (method) => method.PostParser(), "*/1 * * * * *");
RecurringJob.AddOrUpdate<HangFireTaskManager>("MonitorStatus", (method) => method.MonitorStatus(), "*/1 * * * * *");
RecurringJob.AddOrUpdate<HangFireTaskManager>("CommentParser", (method) => method.CommentParser(), "*/1 * * * * *");
RecurringJob.AddOrUpdate<HangFireTaskManager>("LikesParser", (method) => method.LikesParser(), "*/1 * * * * *");


// Init Roles
using (var scope = app.Services.CreateScope())
{
    var services = scope.ServiceProvider;
    try
    {
        var rolesManager = services.GetRequiredService<RoleManager<IdentityRole>>();
        await RoleInitializer.InitializeAsync(rolesManager);
    }
    catch (Exception ex)
    {
        var logger = services.GetRequiredService<ILogger<Program>>();
        logger.LogError(ex, "An error occurred while seeding the database.");
    }
}

app.Run();

大家好。我正在重写项目的架构，当我完成时，我收到了这个错误：

"AggregateException: Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Implemantation.IServices.IOrderService Lifetime: Transient ImplementationType: Implemantation.Services.OrderService': Unable to resolve service for type 'DBInfrastructure.TRepository`1[DBInfrastructure.DTOModels.OrderModel]' while attempting to activate 'Implemantation.Services.OrderService'.)"

"InvalidOperationException: Error while validating the service descriptor 'ServiceType: Implemantation.IServices.IOrderService Lifetime: Transient ImplementationType: Implemantation.Services.OrderService': Unable to resolve service for type 'DBInfrastructure.TRepository`1[DBInfrastructure.DTOModels.OrderModel]' while attempting to activate 'Implemantation.Services.OrderService'."

"AggregateException: Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Implemantation.IServices.IOrderService Lifetime: Transient ImplementationType: Implemantation.Services.OrderService': Unable to resolve service for type 'DBInfrastructure.TRepository`1[DBInfrastructure.DTOModels.OrderModel]' while attempting to activate 'Implemantation.Services.OrderService'.)"

这是斯图普：

public void ConfigureServices(IServiceCollection services)
        {
            services.AddTransient<TRepository<OrderModel>, OrderRepository>();

            services.AddTransient<IOrderService, OrderService>();
        }

这是订单服务：

public class OrderService : IOrderService
    {
        public readonly Random Randomizer = new();
        private readonly TRepository<OrderModel> orderRepository;

        public OrderService(TRepository<OrderModel> orderRepository)
        {
            this.orderRepository = orderRepository;
        }
    }

这是 TRepository：

public class TRepository<T> : IRepository<T> where T : class
    {
        public ISchema Schema { get; set; }
        public ISpace Space { get; set; }
        public IIndex PrimaryIndex { get; set; }
        protected Box box { get; set; }
        private bool disposedValue;

        public  TRepository( Box box, string vspace, string viindex)
        {
            this.box = box;
            _ = Init(vspace, viindex);
        } // ctor
        private async Task Init(string vspace, string viindex)
        {
            Schema = box.GetSchema();
            Space = await box.GetSchema().GetSpace(vspace);
            PrimaryIndex = await Space.GetIndex(viindex);
        } // init func
    }

这是 IRepository：

public interface IRepository<T> : IDisposable where T: class
    {
        public T FindById<Y>(Y id);
        public IEnumerable<T> FindAll();
        public Task Create(T model);
        public Task Delete(T model);
        public Task Update(T moodel);
    }

这是 OrderRepository：

public class OrderRepository : TRepository<OrderModel>
    {
        public OrderRepository(Box box) : base(box, vspace, viindex) { }

        private readonly static string vspace = "orders";
        private readonly static string viindex = "primary_index";
    }

启动 Web 应用程序时发生错误。这是错误的屏幕截图：

大家好。我有这行代码：

 await space.Insert(TarantoolTuple.Create(model.Id, model.Login, model.Balance));

在那里，您需要通过“，”传递插入数据库所需的必要参数。
所有这些参数都是模型对象的属性。
但是，如果我在那里传递对象本身，则不会执行该操作。

public async Task<UserModel> Insert(UserModel model)
        {
            model.Id = Guid.NewGuid().ToString();
            await space.Insert(TarantoolTuple.Create(model));
            return model;
        }

如何解决这个问题？
这个函数稍后会被概括，并且不希望每个实例只为这个函数规定所有属性。

大家好。新更新后，我无法启动网络。常规 IIS 中的应用程序。这是我得到的错误：

HTTP Error 500.30 - ANCM In-Process Start Failure

在 VS 上的 IIS Express 中一切正常，它不想在服务器上运行。可能是什么问题呢？

大家好。我最近不得不使用hangfire 来启动某个任务。

启动任务时，调度程序本身出现以下异常：

Failed
An exception occurred during processing of a background job.

这是整个任务的代码：

    public string name { get; set; }
    public string count { get; set; }

    public EFUserDBContext db;
    public IInfoWithPanelRepository infoWithPanelRepository;
    GetInfoForResourseService(EFUserDBContext db, IInfoWithPanelRepository infoWithPanelRepository)
    {
        this.db = db;
        this.infoWithPanelRepository = infoWithPanelRepository;
    }
    private async Task<String> Request()
    {
        var appSettingsJson = AppSettingsJson.GetAppSettings();
        var ip = appSettingsJson["SMSServiceIP"];
        var apikey = appSettingsJson["ApiKeySMSService"];
        WebRequest request = WebRequest.Create($"http://{ip}/stubs/monitors_ajax.php");
        request.Method = "POST"; // для отправки используется метод Post
                                 // данные для отправки
        string data = $"api_key={apikey}";
        // преобразуем данные в массив байтов
        byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(data);
        // устанавливаем тип содержимого - параметр ContentType
        request.ContentType = "application/x-www-form-urlencoded";
        // Устанавливаем заголовок Content-Length запроса - свойство ContentLength
        request.ContentLength = byteArray.Length;

        //записываем данные в поток запроса
        using (Stream dataStream = request.GetRequestStream())
        {
            dataStream.Write(byteArray, 0, byteArray.Length);
        }

        WebResponse response = await request.GetResponseAsync();
        Stream stream = response.GetResponseStream();
        StreamReader reader = new StreamReader(stream);
        string result = reader.ReadToEnd();
        response.Close();
        return result;
    }
    public async Task GetInfo()
    {
        var jsonstring = await Request();
        Root result = JsonConvert.DeserializeObject<Root>(jsonstring);
        var resourselist = new List<jsonserialize>();
        foreach (var item in result.unprocessed_requests)
        {
            var addedItem = new jsonserialize() { name = item.server_name, count = item.requests_count };
            resourselist.Add(addedItem);
        }
        var json = System.Text.Json.JsonSerializer.Serialize(resourselist);
        InfoWithPanel info = await db.Infos.FirstOrDefaultAsync();
        if (info == null)
        {
            var addedinfo = new InfoWithPanel() { Resourses = json, LastUpdate = DateTime.Now };
            infoWithPanelRepository.Create(addedinfo);
        }
        else
        {
            var updatedinfo = new InfoWithPanel() { id = info.id, Resourses = json, LastUpdate = DateTime.Now };
            infoWithPanelRepository.Update(updatedinfo);
        }
        return;
    }
}

}

可能是什么问题呢？

大家好。我无法弄清楚为什么代码没有被执行。通过某一行后，跳过其余代码，页面加载成功。

        var json = System.Text.Json.JsonSerializer.Serialize(resourselist);
        InfoWithPanel info = await db.Infos.FirstOrDefaultAsync();
//этот код не выполняется
            if (info == null)
            {
                var addedinfo = new InfoWithPanel() { Resourses = json, LastUpdate = DateTime.Now };
                infoWithPanelRepository.Create(addedinfo);
            }
            else
            {
                var updatedinfo = new InfoWithPanel() { id = info.id, Resourses = json, LastUpdate = DateTime.Now };
                infoWithPanelRepository.Update(updatedinfo);
            }
// этот код не выполняется
