Serilog enrichment from context not working

I have a ASP .NET Core application and i am trying to enrich the Serilog logger with a property and pass it throghout method calls. I have used Serilog.Context to enrich it to no avail, the property is not present in the log.

Program

Log.Logger = new LoggerConfiguration().Enrich.FromLogContext()
                .WriteTo.File(logpath)
                .CreateLogger();

Controller

public class SomeController{

   public ILogger logger=Log.ForContext<SomeController>();
   private SomeService Service;

   public SomeController(SomeService serv)
   {
      this.service=serv;
   }

   [HttpGet]
   public async Task DoSomething()
   {
          string corellationId=Guid.NewGuid().ToString();
          LogContext.PushProperty("id",corellationId);
          service.Run();
    }
}

Service

class SomeService
{
   private ILogger logger=Log.ForContext<SomeService>();
   public void Run()
   {
       logger.Information("I AM NOT SEEING the ID from upstream !");
   }
}

Basically i want the logs of SomeService to have the id provided upstream (Controller action). What i want:

"[id] [value]"+ "[SomeService log]"

P.S The service is injected via dependency injection if it matters.

You need to use the Properties token in your outputTemplate, e.g.

var mt = "{LogLevel:u1}|{SourceContext}|{Message:l}|{Properties}{NewLine}{Exception}"

when you format the output for your sink e.g.:

 .WriteTo.File(logpath, outputTemplate: mt)

(ASIDE: You should be using the LogContext.Push return value)
