If I don't have a large enough set of jobs to need the task organizationprovided by Beam::Minion, and althoughMinion can be used as a fully stand-alonelibrary, the easiest solutionis just to build a Mojolicious app. Lucky for me, a Mojolicious app can be just2 lines:
Now, if I never run a web daemon, this will never be a website. So, canthis be called a web application if nobody ever uses a web browser toaccess it? ?
Add Minion
To use Minion, add the Minion plugin to the app. For this example, I'lluse the SQLite Minionbackend so thatI don't need a separate database process running, but Minion can workacross multiple machines if you have a database that accepts remoteconnections.
With the Minion plugin loaded, my application gains some new features:
- I can add Minion tasks (runnable bits of code) with the
minion.add_task
helper - I can enqueue jobs in multiple ways:
- From the command-line with the
minion job
command - From inside the application with the
minion.enqueue
helper - From any Perl script by loading Minion and using the enqueuemethod
- From the command-line with the
- I can run a Minion worker with the
minion worker
command,which will execute any enqueued jobs

Create a Task
I'll create a task called
check_url
to check how long it takes todownload a URL. TheTime::HiRes core module willgive me high resolution times.Enqueuing Jobs

command:Or from inside of another Perl script by loading Minion and using theenqueue method:
Running a Worker
I've enqueued jobs, but nothing's happening, and nothing will happenuntil I run a worker using the

In ASP.NET Core, background tasks can be implemented as hosted services. A hosted service is a class with background task logic that implements the IHostedService interface. This topic provides three hosted service examples:
- Background task that runs on a timer.
- Hosted service that activates a scoped service. The scoped service can use dependency injection (DI).
- Queued background tasks that run sequentially.

Worker Service template
Minion Notifications For Long Running Tasks 1 32-bit
The ASP.NET Core Worker Service template provides a starting point for writing long running service apps. An app created from the Worker Service template specifies the Worker SDK in its project file:
To use the template as a basis for a hosted services app:
- Create a new project.
- Select Worker Service. Select Next.
- Provide a project name in the Project name field or accept the default project name. Select Create.
- In the Create a new Worker service dialog, select Create.
- Create a new project.
- Select App under .NET Core in the sidebar.
- Select Worker under ASP.NET Core. Select Next.
- Select .NET Core 3.0 or later for the Target Framework. Select Next.
- Provide a name in the Project Name field. Select Create.
Use the Worker Service (
worker
) template with the dotnet new command from a command shell. In the following example, a Worker Service app is created named ContosoWorker
. A folder for the ContosoWorker
app is created automatically when the command is executed.Package
An app based on the Worker Service template uses the
Microsoft.NET.Sdk.Worker
SDK and has an explicit package reference to the Microsoft.Extensions.Hosting package. For example, see the sample app's project file (BackgroundTasksSample.csproj).For web apps that use the
Microsoft.NET.Sdk.Web
SDK, the Microsoft.Extensions.Hosting package is referenced implicitly from the shared framework. An explicit package reference in the app's project file isn't required.IHostedService interface
The IHostedService interface defines two methods for objects that are managed by the host:
- StartAsync(CancellationToken):
StartAsync
contains the logic to start the background task.StartAsync
is called before:- The app's request processing pipeline is configured (
Startup.Configure
). - The server is started and IApplicationLifetime.ApplicationStarted is triggered.
The default behavior can be changed so that the hosted service'sStartAsync
runs after the app's pipeline has been configured andApplicationStarted
is called. To change the default behavior, add the hosted service (VideosWatcher
in the following example) after callingConfigureWebHostDefaults
: - The app's request processing pipeline is configured (
- StopAsync(CancellationToken): Triggered when the host is performing a graceful shutdown.
StopAsync
contains the logic to end the background task. Implement IDisposable and finalizers (destructors) to dispose of any unmanaged resources.The cancellation token has a default five second timeout to indicate that the shutdown process should no longer be graceful. When cancellation is requested on the token:- Any remaining background operations that the app is performing should be aborted.
- Any methods called in
StopAsync
should return promptly.
However, tasks aren't abandoned after cancellation is requested—the caller awaits all tasks to complete.If the app shuts down unexpectedly (for example, the app's process fails),StopAsync
might not be called. Therefore, any methods called or operations conducted inStopAsync
might not occur.To extend the default five second shutdown timeout, set:- ShutdownTimeout when using Generic Host. For more information, see .NET Generic Host in ASP.NET Core.
- Shutdown timeout host configuration setting when using Web Host. For more information, see ASP.NET Core Web Host.
The hosted service is activated once at app startup and gracefully shut down at app shutdown. If an error is thrown during background task execution,
Dispose
should be called even if StopAsync
isn't called.BackgroundService base class
BackgroundService is a base class for implementing a long running IHostedService.
ExecuteAsync(CancellationToken) is called to run the background service. The implementation returns a Task that represents the entire lifetime of the background service. No further services are started until ExecuteAsync becomes asynchronous, such as by calling
await
. Avoid performing long, blocking initialization work in ExecuteAsync
. The host blocks in StopAsync(CancellationToken) waiting for ExecuteAsync
to complete.The cancellation token is triggered when IHostedService.StopAsync is called. Your implementation of
ExecuteAsync
should finish promptly when the cancellation token is fired in order to gracefully shut down the service. Otherwise, the service ungracefully shuts down at the shutdown timeout. For more information, see the IHostedService interface section.Timed background tasks
A timed background task makes use of the System.Threading.Timer class. The timer triggers the task's
DoWork
method. The timer is disabled on StopAsync
and disposed when the service container is disposed on Dispose
:The Timer doesn't wait for previous executions of
DoWork
to finish, so the approach shown might not be suitable for every scenario. Interlocked.Increment is used to increment the execution counter as an atomic operation, which ensures that multiple threads don't update executionCount
concurrently.The service is registered in
IHostBuilder.ConfigureServices
(Program.cs) with the AddHostedService
extension method:Consuming a scoped service in a background task
To use scoped services within a BackgroundService, create a scope. No scope is created for a hosted service by default.
The scoped background task service contains the background task's logic. In the following example:
Minion Notifications For Long Running Tasks 1 360
- The service is asynchronous. The
DoWork
method returns aTask
. For demonstration purposes, a delay of ten seconds is awaited in theDoWork
method. - An ILogger is injected into the service.
The hosted service creates a scope to resolve the scoped background task service to call its
DoWork
method. DoWork
returns a Task
, which is awaited in ExecuteAsync
:The services are registered in
IHostBuilder.ConfigureServices
(Program.cs). The hosted service is registered with the AddHostedService
extension method:Queued background tasks
A background task queue is based on the .NET 4.x QueueBackgroundWorkItem:
Splayer 4 2 0 8. In the following
QueueHostedService
example:- The
BackgroundProcessing
method returns aTask
, which is awaited inExecuteAsync
. - Background tasks in the queue are dequeued and executed in
BackgroundProcessing
. - Work items are awaited before the service stops in
StopAsync
.
A
MonitorLoop
service handles enqueuing tasks for the hosted service whenever the w
key is selected on an input device:- The
IBackgroundTaskQueue
is injected into theMonitorLoop
service. IBackgroundTaskQueue.QueueBackgroundWorkItem
is called to enqueue a work item.- The work item simulates a long-running background task:
- Three 5-second delays are executed (
Task.Delay
). - A
try-catch
statement traps OperationCanceledException if the task is cancelled.
- Three 5-second delays are executed (
The services are registered in
IHostBuilder.ConfigureServices
(Program.cs). The hosted service is registered with the AddHostedService
extension method:MonitorLoop
is started in Program.Main

Hosted services implement the IHostedService interface. The interface defines two methods for objects that are managed by the host:
- StartAsync(CancellationToken):
StartAsync
contains the logic to start the background task. When using the Web Host,StartAsync
is called after the server has started and IApplicationLifetime.ApplicationStarted is triggered. When using the Generic Host,StartAsync
is called beforeApplicationStarted
is triggered. - StopAsync(CancellationToken): Triggered when the host is performing a graceful shutdown.
StopAsync
contains the logic to end the background task. Implement IDisposable and finalizers (destructors) to dispose of any unmanaged resources.The cancellation token has a default five second timeout to indicate that the shutdown process should no longer be graceful.

Startup.ConfigureServices
. The IHostedService
implementation is registered with the AddHostedService
extension method:Queued background tasks
A background task queue is based on the .NET Framework 4.x QueueBackgroundWorkItem (tentatively scheduled to be built-in for ASP.NET Core):
In
QueueHostedService
, background tasks in the queue are dequeued and executed as a BackgroundService, which is a base class for implementing a long running IHostedService
:The services are registered in
Startup.ConfigureServices
. The IHostedService
implementation is registered with the AddHostedService
extension method:In the Index page model class:
- The
IBackgroundTaskQueue
is injected into the constructor and assigned toQueue
. - An IServiceScopeFactory is injected and assigned to
_serviceScopeFactory
. The factory is used to create instances of IServiceScope, which is used to create services within a scope. A scope is created in order to use the app'sAppDbContext
(a scoped service) to write database records in theIBackgroundTaskQueue
(a singleton service).
When the Add Task button is selected on the Index page, the
OnPostAddTask
method is executed. QueueBackgroundWorkItem
is called to enqueue a work item:
