I recently noticed around the time I updated to NLog.Web/NLog.Web.AspNetCore 4.8.5 that the debug logger stopped working in addition to the NLog configuration. I could add an NLog debugger target, but I prefer the layout and configuration of the base provider. Is there anyway to restore this?

My WebHost configuration appears as follows:

public static IWebHostBuilder CreateWebHostBuilder(string[] args)
    => WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .ConfigureLogging((context, logging) =>
        {
            logging.ClearProviders();
            logging.SetMinimumLevel(LogLevel.Trace);

            if (context.HostingEnvironment.IsDevelopment())
            {
                logging.AddDebug();
            }

            NLog.LogManager.Configuration = new NLogLoggingConfiguration(context.Configuration.GetSection("NLog"));
        })
        .UseNLog();

@jcasale Does it work with NLog.Web.AspNetCore ver. 4.8.4 ?

[jcasale]

Hi @snakefoot Yes I can confirm AddDebug logging is visible after reverting to 4.8.4.

[snakefoot]

Created PR #485 to fix this change in behavior.

Thank you for reporting this.

[304NotModified]

This will be fixed in 4.8.6. See #487

Currently working on the release
