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 scopedService = scope.ServiceProvider.GetRequiredService<IMyScopedService>();
await scopedService.DoWork(stoppingToken);
}
}
public override async Task StopAsync(CancellationToken stoppingToken)
{
await base.StopAsync(stoppingToken);
}
}
|
| Program.cs |
services.AddHostedService<MyBackgroundService>(); services.AddScoped<IMyScopedService, MyScopedService>(); |
