EasyExtensions.BackgroundServiceExtensions 0.1.0

BackgroundServiceExtensions

Step by step guide

1. Install nuget package

Install-Package EasyExtensions.BackgroundServiceExtensions

2. Create a class which will be executed by schedule:

public class MyBackgroundService : ScheduledJobServiceBase
{
    private readonly IServiceProvider _serviceProvider;

    public MyBackgroundService(ScheduledJobOptions<MyBackgroundService> options, 
        ILogger logger, 
        IServiceProvider serviceProvider) : 
        base(options.Expression, logger)
    {
        _serviceProvider = serviceProvider;
    }

    public override Task ExecuteJobAsync(CancellationToken cancellationToken)
    {
        using (var scope = _serviceProvider.CreateScope())
        {
            // code to be executed by schedule
        }

        return Task.CompletedTask;
    }
}

3. Register the class in the Startup:

public void ConfigureServices(IServiceCollection services)
{
    // other registrations

    services.RegisterScheduledJob<MyBackgroundService>(Configuration);
}

4. Add a section to appsettings.json:

  {    
    //other configuration

    "ScheduledJobs": {
      "MyBackgroundService": {
        "Expression": "*/1 * * * *",
        "Enabled": true
      }
    }
  }

5. Change CRON expression to whatever you want to.

If you are not familiar with CRON expression I can recommend this tool to start with.
