# Scheduling with Timers


This sample illustrates the use of a [.NET Timer](https://learn.microsoft.com/en-us/dotnet/api/system.threading.timer) to trigger scheduled tasks. To leverage the benefits of [NServiceBus retries](/nservicebus/recoverability/index.md) and [consistency of outgoing messages with the transport transaction](/transports/transactions.md), the tasks are implemented as regular message handlers. This also gives full traceability of the invoked tasks in platform tools like [ServicePulse](/servicepulse/index.md).

<!-- snippet: ScheduleUsingTimer -->

```cs
var interval = TimeSpan.FromSeconds(5);

var timer = new Timer(async state =>
{
    try
    {
        await messageSession.SendLocal(new MyScheduledTask());

        logger.LogInformation("{Task} scheduled", nameof(MyScheduledTask));
    }
    catch (Exception ex)
    {
        logger.LogError(ex, nameof(MyScheduledTask) + " could not be scheduled");
    }
}, null, interval, interval);
```
