DotNetCore.WindowsService

Simple library that allows one to host dot net core application as windows services. Perfect solution to power micro-services architecture.

Important note

This library was created to enable one to host CONSOLE dot net core applications. If you want to host a WEBSITE as a service, you're better of following https://docs.microsoft.com/en-us/aspnet/core/hosting/windows-service

Installation

Using nuget: Install-Package PeterKottas.DotNetCore.WindowsService

Quick start

Easiest way to start is using a brand new template. Just do :

dotnet new -i PeterKottas.DotNetCore.WindowsService.Templates::*

This will add one template at the moment.

Follow up with this

mkdir NameOfYourProject
cd NameOfYourProject
dotnet new mcrsvc-min

This will create a sample project for you. Next chapter explains its features in more details especially points 6 onwards if you used the template.

Community, feel encouraged to add more templates if you find something missing/usefull. I'll be more than happy to add these. Just copy the project in https://github.com/PeterKottas/DotNetCore.WindowsService/tree/master/Source/Templates/PeterKottas.DotNetCore.WindowsService.MinimalTemplate and follow instructions in https://github.com/dotnet/templating if you need more specific behvaiour.

Usage

1. Create .NETCore console app.

2. Create your first service, something like this:

   public class ExampleService : IMicroService
   {
   	public void Start()
   	{
   		Console.WriteLine("I started");
   	}
   	
   	public void Stop()
   	{
   		Console.WriteLine("I stopped");
   	}
   }

3. You can also inherit MicroService base class and take advantage of built in timers:

   public class ExampleService : MicroService, IMicroService
   {
   	public void Start()
   	{
   		this.StartBase();
   		Timers.Start("Poller", 1000, () =>
   		{
   			Console.WriteLine("Polling at {0}\n", DateTime.Now.ToString("o"));
   		},
   		(e) =>
   		{
   			Console.WriteLine("Exception while polling: {0}\n", e.ToString());
   		});
   		Console.WriteLine("I started");
   	}
   	
   	public void Stop()
   	{
   		this.StopBase();
   		Console.WriteLine("I stopped");
   	}
   }

4. Api for services (and yeah, it's simmilar to Topshelf, thanks for inspiration, I just couldn't wait for you guys to implement this):

   ServiceRunner<ExampleService>.Run(config =>
   {
   	var name = config.GetDefaultName();
   	config.Service(serviceConfig =>
   		{
   			serviceConfig.ServiceFactory((extraArguments) =>
   		{
   			return new ExampleService();
   		});
   		serviceConfig.OnStart((service, extraArguments) =>
   		{
   			Console.WriteLine("Service {0} started", name);
   			service.Start();
   		});
   
   		serviceConfig.OnStop(service =>
   		{
   			Console.WriteLine("Service {0} stopped", name);
   			service.Stop();
   		});
   		
   		serviceConfig.OnInstall(service =>
   		{
   			Console.WriteLine("Service {0} installed", name);
   		});
   		
   		serviceConfig.OnUnInstall(service =>
   		{
   			Console.WriteLine("Service {0} uninstalled", name);
   		});
   		
   		serviceConfig.OnPause(service =>
   		{
   			Console.WriteLine("Service {0} paused", name);
   		});
   		
   		serviceConfig.OnContinue(service =>
   		{
   			Console.WriteLine("Service {0} continued", name);
   		});
   
   		serviceConfig.OnError(e =>
   		{
   			Console.WriteLine("Service {0} errored with exception : {1}", name, e.Message);
   		});
   	});
   });

5. Optionally set the name of the service like this:

   ServiceRunner<ExampleService>.Run(config =>
   {
   	config.SetName("MyTestService");
   });

6. Run the service without arguments and it runs like console app.

7. Run the service with action:install and it will install the service.

8. Run the service with action:uninstall and it will uninstall the service.

9. Run the service with action:start and it will start the service.

10. Run the service with action:stop and it will stop the service.

11. Run the service with username:YOUR_USERNAME, password:YOUR_PASSWORD and action:install which installs it for the given account.

12. Run the service with built-in-account:(NetworkService|LocalService|LocalSystem) and action:install which installs it for the given built in account. Defaults to LocalSystem.

13. Run the service with description:YOUR_DESCRIPTION and it setup description for the service.

14. Run the service with display-name:YOUR_DISPLAY_NAME and it setup Display name for the service.

15. Run the service with name:YOUR_NAME and it setup name for the service.

16. Run the service with start-immediately:(true|false) to start service immediately after install. Defaults to true.

17. You can find the complete example in PeterKottas.DotNetCore.Example project.

18. Install the service using powershell: dotnet.exe $serviceDllPath action:install
