I can not use ISettingManager in QuartzBackgroundWorkerBase，What is the correct way to init Trigger with settingManager info?

Is there an existing issue for this?

Description

 public class OrderExpCheckerWorker : QuartzBackgroundWorkerBase
 {
     IOrderRepository _orderRepository;
     ISettingManager _settingManager;
     IServiceProvider _serviceProvider;

     public OrderExpCheckerWorker(ISettingManager settingManager, IOrderRepository orderRepository, IServiceProvider serviceProvider) : base()
     {
         _settingManager = settingManager;
         _orderRepository = orderRepository;
         _serviceProvider = serviceProvider;

         AutoRegister = true;

         /// got deadlock
         var p = _settingManager.GetOrNullGlobalAsync("ccccc").GetAwaiter().GetResult();

         JobDetail = JobBuilder.Create<OrderExpCheckerWorker>().WithIdentity(nameof(OrderExpCheckerWorker)).Build();
         Trigger = TriggerBuilder.Create()
                 .WithIdentity(nameof(OrderExpCheckerWorker))
                 .WithSimpleSchedule(s => s.WithIntervalInMinutes(Convert.ToInt32(p))
                                         .RepeatForever()
                                         .WithMisfireHandlingInstructionIgnoreMisfires()
                                     )
                 .Build();
     }


     public override Task Execute(IJobExecutionContext context)
     {
         Logger.LogInformation("test");
         return Task.CompletedTask;
     }
 }

when run var p = _settingManager.GetOrNullGlobalAsync("ccccc").GetAwaiter().GetResult(); got deadlock

What is the correct way to init Trigger with settingManager info?

I have been tried several way to run _settingManager.GetOrNullGlobalAsync("ccccc").GetAwaiter().GetResult() but got all fail。

It seems the definition is later construct than the backgroundwork construct

try getting settings in the task and not in the ctor

try getting settings in the task and not in the ctor

tried but all fail. for example AsyncHelper , Task ,
I think it's better to have a async methord to init the backgroundworker,not in the constructor.

solve by strange way
in order to start define settings before worker start, change AutoRegister to false. and start in postapplication event.
in order to execute async methord , config schedule job to flowing

`
public OrderExpCheckerWorker(ISettingManager settingManager, IOrderRepository orderRepository, IServiceProvider serviceProvider) : base()
{
_settingManager = settingManager;
_orderRepository = orderRepository;
_serviceProvider = serviceProvider;

        AutoRegister = false;

        JobDetail = JobBuilder.Create<OrderExpCheckerWorker>().WithIdentity(nameof(OrderExpCheckerWorker)).Build();
        Trigger = TriggerBuilder.Create()
                .WithIdentity(nameof(OrderExpCheckerWorker))
                .Build();
        ScheduleJob = async scheduler =>
        {
            if (!await scheduler.CheckExists(JobDetail.Key))
            {
                var p = await _settingManager.GetOrNullGlobalAsync(EShopConsts.OrderExpireCheckPeriodSetting);
                Trigger = TriggerBuilder.Create()
                .WithIdentity(nameof(OrderExpCheckerWorker))
                .WithSimpleSchedule(s => s.WithIntervalInMinutes(Convert.ToInt32(p))
                                        .RepeatForever()
                                        .WithMisfireHandlingInstructionIgnoreMisfires()
                                    )
                .Build();
                await scheduler.ScheduleJob(JobDetail, Trigger);
            }
        };
    }

`

another way is change Trigger before manual start
