Nlog 3.1 with Castle Windsor not logging

问题

I'm trying to use NLog (3.1) with Windsor Castle Facility, but it's not working for me (no errors, nothing happens)

These are my steps so far:

Downloaded from Nuget: Castle Windsor NLog integration
Downloaded from Nuget: NLog Configuration

Updates nlog config like this:

<target xsi:type="File" name="f" fileName="d:\nlog.log"
        layout="${longdate}|${level:uppercase=true}|${logger}|${message}" />

<logger name="*" minlevel="Trace" writeTo="f" />

Added Windsor Installer

 public class LoggingInstaller : IWindsorInstaller
 {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.AddFacility<LoggingFacility>(f => f.LogUsing(LoggerImplementation.NLog).WithConfig("NLog.config"));
        }
}

Which I'm calling it (I've checked that a breakpoint in there is being hit.

Added the logger class like this:

namespace WebApi.App_Start
{
    public class MyLogger
    {
        private ILogger logger = NullLogger.Instance;

        public ILogger Logger
        {
            get { return logger; }
             set { logger = value; }
        }
    }
}

Using it in a controller like this:

new MyLogger().Logger.Info("New Request Created.");

But I don't see the file created.

Any step missing?

Thanks in advance. Guillermo.

You need to put the Logger property to every class where you want to log something and the instances of the class has to be created/managed by Windsor.

So you need to add it to your controller:

public class MyController : Controller
{
    private ILogger logger = NullLogger.Instance;

    public ILogger Logger
    {
        get { return logger; }
        set { logger = value; }
    }

    public ActionResult MyAction() 
    {
         Logger.Info("New Request Created.");
    }
}

It was not working with the MyLogger because that class was not managed/created by Windsor so it was not injected your Logger property. But because the controller isntances are created by Windsor and ILogger inejtion is wokring in them: Windsor Tutorial - Part Five - Adding logging support
