With this post I hope to draw attention to the ability to use dependency injection with Sitecore’s Scheduling Agents, for more information about agents see Johns blog post.

Most solutions now use DI with MVC controllers which is great, but I have noticed it is not used with agents?

Which is a pity as it is very simple to do this in Sitecore 9.0, Just add resolve =”true”.

Then add any dependencies to your constructor as required.

private readonly ILogger _logger;
private readonly UpdateSeatAvailabilityService _updateSeatAvailabilityService;

public UpdateSeatAvailabilityAgent(
       [NotNull]ILogger logger, 
       [NotNull]UpdateSeatAvailabilityService updateSeatAvailabilityService)
        {
            Assert.ArgumentNotNull(logger, nameof(logger));
            Assert.ArgumentNotNull(updateSeatAvailabilityService, nameof(updateSeatAvailabilityService));
            _logger = logger;
            _updateSeatAvailabilityService = updateSeatAvailabilityService;
        }

Hope this helps, Alan
