Description

In ASP.NET Core, background tasks can be implemented as hosted services.

Consuming a scoped service in a background task

MyBackgroundService.cs
public class MyBackgroundService(IServiceProvider services) : BackgroundService
{
    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        using (var scope = Services.CreateScope())
        {
            var scopedProcessingService = scope.ServiceProvider.GetRequiredService<IScopedProcessingService>();
            await scopedProcessingService.DoWork(stoppingToken);
        }
    }

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