Я использую NLog в. NET Базовая веб-служба, опубликованная как одиночная файл и попытка установить его как службу. NLog отлично работает, когда я запускаю его в обычном режиме, однако при запуске в качестве службы ему нужно указать, где найти файл конфигурации, что я выполняю с помощью: 

            var pathToExe = Process.GetCurrentProcess().MainModule.FileName;
            var pathToContentRoot = Path.GetDirectoryName(pathToExe);

            NLog.LogManager.Configuration = new NLog.Config.XmlLoggingConfiguration(Path.Combine(pathToContentRoot, "nlog.config"));
            var logger = NLog.Web.NLogBuilder.ConfigureNLog(NLog.LogManager.Configuration).GetCurrentClassLogger();

И содержимого root с помощью: 

                builder.UseWindowsService().UseContentRoot(pathToContentRoot);

Кажется, что это работает, по крайней мере, сначала, и генерирует некоторый вывод журнала, достаточный, чтобы увидеть, что я устанавливаю содержимое root успешно: 

2020-05-28 15:42:20.5932 SkyJack.Agent.Program INFO ... Initializing SkyJack Agent with content root G:\MSGPS2\SkyJack\SkyJack\src\SkyJack.Agent\bin\Release\netcoreapp3.1\publish...

2020-05-28 15:42:20.9446 SkyJack.Agent.Program TRACE Returned from builder.Build()

В конце концов, тем не менее, он выдает исключение:

WebAppService.Startup.Configure () снова вызывает NLog.Web.NLogBuilder.ConfigureNLog (), предположительно с просто «nlog.config» вместо местоположения или LoggerConfiguration объект, который я передал для начала.

Есть ли способ заставить его использовать местоположение или конфигурацию, которые я уже указал и загрузил?

Мне удалось заставить его работать, используя: 

            NLog.LogManager.LogFactory.SetCandidateConfigFilePaths(new List<string> { $"{Path.Combine(pathToContentRoot, "nlog.config")}" });
            var logger = NLog.Web.NLogBuilder.ConfigureNLog("nlog.config").GetCurrentClassLogger();
...
