January 20, 2010 At Dovetail we use StructureMap a lot. Lately we’ve also been using Topshelf a lot too. This post takes a look at how you can marry these two technologies together. We will be using the StrucutreMap container to configure which services get started by Topshelf at runtime. Simple Services   Let’s start simple. We need a way to identify which configured types want to get configured to be spun up by Topshelf. To accomplish this I created an interface called ISimpleService which includes only the Start and Stop methods that Topshelf uses to manage the services lifetime.   public interface ISimpleService { void Start(); void Stop(); }   Next up we’ll update and expand the example from my previous post Controlling Application Lifetime In Topshelf to have it implement the ISimpleService. We’ll also add another service in charge of spamming the log file.   public class LogSpamService :…

One of Topshelf’s best features is the ability to easily host one or more services running side by side. In this post we will create a Topshelf service which will shut down the application. Lets take a look at how it is done.     Coordinating the Service   Let’s create a fake Health Monitoring service which will, sometime in the future, tell Topshelf to shut the application down. The Topshelf hook for controlling the state of all the services it is hosting is a type called IServiceCoordinator. Here is the code for our health monitor. public class HealthMonitoringService : IHealthMonitoringService { private readonly IServiceCoordinator _serviceCoordinator; private readonly ILogger _logger; private Timer _timer; private int _healthCheckCount = 0; public HealthMonitoringService(IServiceCoordinator serviceCoordinator, ILogger logger) { _serviceCoordinator = serviceCoordinator; _logger = logger; } public void Start() { _logger.LogWarn("The Health Monitor is starting up");…
