How to use Topshelf.Logging properly

Question

Any clue how to use Topshelf.Logging properly?

Do I have to pass NLogLogWriter to the constructor of the service class?

And how to enable output to console as well?

class Program
    {
        #region Properties
        Topshelf.Logging.NLogLogWriter logger;
        static string mainLoggerName = "MainLogger";
        #endregion

        static void Main(string[] args)
        {
            var  nlogLogger = LogManager.GetCurrentClassLogger();
            Topshelf.Logging.NLogLogWriter logger = new Topshelf.Logging.NLogLogWriter(nlogLogger, mainLoggerName);


            HostFactory.Run(x =>                                 
            {
                x.Service<ExSPCAgentService>(s =>                         
                {
                    s.ConstructUsing(name => new MyAgentService());      

                    // s.WhenStarted(tc => tc.Start());               
                    s.WhenStarted(tc =>
                    {
                        // Add more config options if you need
                        tc.Start();
                    });
                    s.WhenStopped(tc => tc.Stop());                
                });
                x.RunAsLocalSystem();                             
                x.UseNLog();
                x.SetDescription("MyAgentService");         
                x.SetDisplayName("MyAgentService");                        
                x.SetServiceName("MyAgentService");                        

            });
        }
    }

To specify your logger, use the overload of UseNLog that lets you specify a LogFactory.

For logging to console you would enable a console target.

Edit: docs

NLog Integration

To enable logging via NLog, the Topshelf.NLog NuGet package is available. Once added to your project, configure Topshelf to use NLog via the configuration:

HostFactory.New(x =>
{
    x.UseNLog();
});

This will change the HostLogger to use NLog. An existing LogFactory can be passed as well, using an overload of the same method.

Thank you! The second part about the console target was useful. Would u mind to provide an example about LogFactory, please. – Guanabana

When using x.UseNLog(existingLogFactory), it isn't possible to reach this factory in another class. I tried to use LogManager.GetCurrentClassLogger(), but the LogManagers configuration is null. What must be done to can use the exist logFactory in other classes and modules? Btw, I use Lamar as IoC. Thanks :) – Crustacean

Well, you could make the log factory a static class member? – Capitalization
