Gotta love the guys that would rather pick at the question than answer it ... sigh. In case anyone else needs this

      public static class ConsoleLoggerExtensions  
     {  
         public static ILoggingBuilder AddCustomFormatter(  
             this ILoggingBuilder builder) =>  
             builder.AddConsole(options => options.FormatterName = nameof(CustomLoggingFormatter))  
                 .AddConsoleFormatter<CustomLoggingFormatter, ConsoleFormatterOptions>();  
     }  
     public sealed class CustomLoggingFormatter : ConsoleFormatter, IDisposable  
     {  
         private readonly IDisposable _optionsReloadToken;  
         private ConsoleFormatterOptions _formatterOptions;  
         public CustomLoggingFormatter(IOptionsMonitor<ConsoleFormatterOptions> options)  
     // Case insensitive  
     : base(nameof(CustomLoggingFormatter)) =>  
     (_optionsReloadToken, _formatterOptions) =  
         (options.OnChange(ReloadLoggerOptions), options.CurrentValue);  
         private void ReloadLoggerOptions(ConsoleFormatterOptions options) =>  
     _formatterOptions = options;  
   
         public override void Write<TState>(  
     in LogEntry<TState> logEntry,  
     IExternalScopeProvider scopeProvider,  
     TextWriter textWriter)  
         {  
             string? message =  
                 logEntry.Formatter?.Invoke(  
                     logEntry.State, logEntry.Exception);  
   
             if (message is null)  
             {  
                 return;  
             }  
   
             textWriter.WriteLine($"{message}");  
         }  
         public void Dispose() => _optionsReloadToken?.Dispose();  
     }  
  

then in .ConfigureServices(services =>

            services.AddLogging(opt =>  
            {  
                opt.AddCustomFormatter();  
            }

Hi,EusebiuMarcu

Could you please tell me why you want to show the log without the category? the log is used to determine whether the code can work or not and then locate

the error. You need the information of the category to check where the problem lies. If you really want to delete it ,then you can check this link to custom the

logger:

custom-logging-provider
