Missing trace\debug logs in ASP.NET Core 2?

Missing the trace and debug logs in .NET Core 2?

Check your appsettings.json

The following is advised:

{
    "Logging": {
        "LogLevel": {
            "Default": "Trace",
            "Microsoft": "Information"
        }
    }
}

⚠️ Make sure also to check any environment specific appsettings.json. Ex. appsettings.development.json

Notice NLog.Web.AspNetCore ver. 4.12 introduces the new options ReplaceLoggerFactory and RemoveLoggerFactoryFilter for NLogAspNetCoreOptions. This allows NLog to be excluded from any filtering configured for Microsoft LoggerFactory. Example:

.UseNLog(new NLogAspNetCoreOptions() { RemoveLoggerFactoryFilter = true });
