Getting Started

All task configuration is handled in a registry class. You can use classes that implement FluentScheduler.ITask or express your task as an Action . An example registration class would be:

using FluentScheduler;

public class MyRegistry : Registry
{
	public MyRegistry()
	{
		// Schedule an ITask to run at an interval
		Schedule<MyTask>().ToRunNow().AndEvery(2).Seconds();

		// Schedule a simple task to run at a specific time
		Schedule(() => Console.WriteLine("Timed Task - Will run every day at 9:15pm: " + DateTime.Now)).ToRunEvery(1).Days().At(21, 15);

		// Schedule a more complex action to run immediately and on an monthly interval
		Schedule(() =>
		{
			Console.WriteLine("Complex Action Task Starts: " + DateTime.Now);
			Thread.Sleep(1000);
			Console.WriteLine("Complex Action Task Ends: " + DateTime.Now);
		}).ToRunNow().AndEvery(1).Months().OnTheFirst(DayOfWeek.Monday).At(3, 0);
	}
} 

You then need to initialize the task manager. This is usually done in the Application_Start method of a web application or when your application is being loaded:

protected void Application_Start()
{
	TaskManager.Initialize(new MyRegistry()); 
} 

Using your Dependency Injection / Inversion of Control tool of choice

FluentScheduler makes it easy to use your IOC tool to create task instances. Simply override the GetTaskInstance<T>() method on your Registry class. An example incorporating StructureMap:

using FluentScheduler;
using StructureMap;

public class MyRegistry : Registry
{
	public MyRegistry()
	{
		// Schedule an ITask to run at an interval
		Schedule<MyTask>().ToRunNow().AndEvery(2).Seconds();
	}

	public override ITask GetTaskInstance<T>()
	{
		return ObjectFactory.Container.GetInstance<T>();
	}
} 

Handling unexpected exceptions thrown from tasks

To observe unhandled exceptions from your scheduled tasks, you will need to hook the UnobservedTaskException event on TaskManager. That event will give you access to the underlying System.Threading.Tasks.Task and thrown exception details. Example code that handles unexpected exceptions:

protected void Application_Start()
{
	TaskManager.UnobservedTaskException += TaskManager_UnobservedTaskException;
	TaskManager.Initialize(new TaskRegistry());
}

static void TaskManager_UnobservedTaskException(Task sender, UnhandledExceptionEventArgs e)
{
	Log.Fatal("An error happened with a scheduled task: " + e.ExceptionObject);
}
