Nortal.Utilities.TaskSchedulerEngine

This assembly provides tools to build a task scheduler engine for triggering prepared tasks at specified time and/or intervals. Tools are provided to support hosting as a windows service.

Requirements:

• Microsoft .Net Framework 4 Client Profile.

Main features

• Can set tasks execution time
• Can configure tasks to automatically reschedule itself to run after fixed interval.
• Task execution logs
• Tools to simplify running as a windows service
• tools for graceful engine stopping without interrupting ongoing tasks
• option to automatically discover all tasks from host assembly
• Example project to help getting started
• It is with open source (Apache v2.0 licence)
• Available also from Nuget: https://www.nuget.org/packages/Nortal.Utilities.TaskSchedulerEngine

Getting started

• Create a console application project

• Reference Nortal.Utilities.TaskSchedulerEngine.dll -or- install nuget package

    PM> Install-Package Nortal.Utilities.TaskSchedulerEngine
  

• Implement tasks by using ISchedulerTask interface:

    public class MyTask : ISchedulerTask
    {
    	public bool IsEnabled { get { return true; } }
    	public DateTime ExecutionTime { get { return DateTime.Now; } }
    	public TimeSpan Interval { get { return TimeSpan.FromSeconds(5); } }
    
    	public void Run(StringBuilder log)
    	{
    		log.Append("Hello, world!");
    	}
    }
  

• run the scheduler engine to start executing the prepared task.

    // service that contains a single engine which automatically discovers ISchedulerTask implementations
    var engine = new AllHostTasksSchedulerEngine();
    engine.Run();
  

• All done!

Check the example application included with source code for other examples.

Extension points

• Can configure engine ticking interval
• Task configuration entirely left up to programmer. You can hardcode values, user xml configuration, database or any other configuration source.
• Option to replace the default logging (CSV files) by implementing your own logger using ISchedulerEngineLogger interface.
