Background Job Services With Asp Net 6

first you need add class Background Worker and inheritance class "BackgroundService" in namespace "Microsoft.Extensions.Hosting" like this :

task this job is calculate salary employees .

public class SalaryCalculateBackgroundWorker : BackgroundService
{
}

next you need add this class in Service Collection like this :

services.AddHostedService<SalaryCalculateBackgroundWorker>();

now your job add in project add need set run configs .

when you inherited class SalaryCalculateBackgroundWorker from "BackgroundService" you should override 3 method like this

public override Task StartAsync(CancellationToken cancellationToken)
{
    return base.StartAsync(cancellationToken);
}

public override async Task StopAsync(CancellationToken cancellationToken)
{
    await base.StopAsync(cancellationToken);
}

protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
}

method ExecuteAsync for run method in different times .

your start method and stop method for start and stop job .

you need exception handler for try catch .

you need set delay for run again" while" .

i call await _salaryCalculateService.SalaryCalculateAsync(); in 5 FromSeconds for test.

protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
    try
    {
        await DoWork(stoppingToken);
    }
    catch (Exception exception)
    {
        //exception 
    }
}

#region [ Private ]

private async Task DoWork(CancellationToken stoppingToken)
{
    while (!stoppingToken.IsCancellationRequested)
    {
        await _salaryCalculateService.SalaryCalculateAsync();

        await Task.Delay(TimeSpan.FromSeconds(5), stoppingToken);
    }
}
#endregion [ Private ]

Good luck
