ABP Framework version: v5.3.1
UI type: Angular
DB provider: EF Core

HI how can I add a recurring job at run time? and how can I remove it?

so I try to add via startup but I try to read polling intervall via appsettings.json but I can't do it

 public PollingWorker()
    {
        //_options = ServiceProvider.GetService<IOptions<Dataptions>>().Value; --> Null exception
        RecurringJobId = nameof(PollingWorker);
        CronExpression = Cron.MinuteInterval(2);
    }

Did you use hangfire or Quartz?

You can refer to the Hangfire API. https://docs.hangfire.io/en/latest/index.html

You can try to inject IConfiguration to reading the appsettings

How can I inject Iconfiguration?

 public override async Task OnApplicationInitializationAsync(
        ApplicationInitializationContext context)
    {
        await context.AddBackgroundWorkerAsync<PollingWorker>();
    }

If I add an IServiceProvider I get this error

annot resolve parameter 'Microsoft.Extensions.DependencyInjection.IServiceCollection service' of constructor 'Void .ctor(Microsoft.Extensions.DependencyInjection.IServiceCollection)'.
