What am I doing wrong with logging? console OK. NLog not writing the log to files. Help. using .net core 7 console app.

      var logger = LoggerFactory.Create(builder =>
            {
                builder.AddNLog("NLog.config");
                builder.AddConsole();
                **builder.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Debug);**
            });

builder.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Debug); this does not work anymore

I can get logging to the console, but no logging to files.

appsettings.json:
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Information",
      "Microsoft.Hosting.Lifetime": "Information",
      "Quartz": "Information",
      "Quartz.Core.QuartzSchedulerThread": "Information",
      "Quartz.Core.JobRunShell": "Information"
    },

code:

            var logger = LoggerFactory.Create(builder =>
            {
                builder.AddNLog("NLog.config");  // this reads the configuration. 
                builder.AddConsole(); // works.
                builder.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Debug);

            });
            
            Quartz.Logging.LogContext.SetCurrentLogProvider(logger);

nothing logs to files.
