This how-to entry will detail the steps for getting Topshelf installed, running, and a schedule integrated and timed appropriately using Quartz. Once that is complete I’ll go over how to get custom schedules added to the service.

Topshelf

To get Topshelf up and running open up Visual Studio, start a Windows Console Project, and then use Nuget (if you don’t have Nuget installed, I suggest doing that ASAP, you’ll need it to follow along with any reference additions).

Once you have Topshelf and associated references added via Nuget create a new class file called StatusCheckIn and add the following code.

[sourcecode language=”csharp”]
using System;
using System.Timers;

namespace Sample.Services
{
public class StatusCheckIn
{
readonly Timer _timer;

public StatusCheckIn()
{
_timer = new Timer(5000) { AutoReset = true };
_timer.Elapsed += TimeHappened;
}

static void TimeHappened(object sender, EventArgs eventArgs)
{
Console.WriteLine("Status Time: {0} checking in.",
DateTime.Now);
Console.WriteLine("Sender Type: {0}",
sender.GetType());
Console.WriteLine("Event Argument Type: {0}",
eventArgs);
}

public void Start()
{
_timer.Start();
}

public void Stop()
{
_timer.Stop();
}
}
}
[/sourcecode]

After adding the StatusCheckIn Class, open up the Program.cs file and add or change the following code.

[sourcecode language=”csharp”]
using Topshelf;

namespace Sample.Services
{
class Program
{
static void Main()
{
HostFactory.Run(hostConfigurator =>
{
hostConfigurator.Service<StatusCheckIn>(
serviceConfigurator =>
{
serviceConfigurator.SetServiceName("TS");
serviceConfigurator.ConstructUsing(
name => new StatusCheckIn());
serviceConfigurator.WhenStarted(tc => tc.Start());
serviceConfigurator.WhenStopped(tc => tc.Stop());
});

hostConfigurator.RunAsLocalSystem();
hostConfigurator.SetDescription("Sample Host");
hostConfigurator.SetDisplayName("Display Name");
hostConfigurator.SetServiceName("Topshelf Service");
});
}
}
}
[/sourcecode]

If you run into an odd reference error, it is likely that VS2010 has determined you want the client profile of .NET 4.0 again. If anyone at MS on the VS2010/.NET 4.0 reads this, we DO NOT want this to be the default. It’s ridiculous that it gets set as default without some type of manual change. But I digress, open up the properties of the console/service project and set it under the dialog as shown.

NOTES: Working code available on Github under my Topshelf Repo.
