Program.cs

 builder.Services.AddLogging(logger =>
            {
                logger.ClearProviders();

                Log.Logger = new LoggerConfiguration()
                   .ReadFrom.Configuration(builder.Configuration)
                   .Enrich.FromLogContext()
                   .WriteTo.Console()
                   .CreateLogger();

                logger.AddSerilog();

                Log.Logger.Information("Serilog Initialized.");
            });


 builder.Host.UseSerilog();

 var app = builder.Build();
 app.UseSerilogRequestLogging();

Default logging configuration have been removed from appsetting.json. Please help me to remove default Microsfot logging behavior and allow only Serilog logs

Answer 1

you need remove WriteTo.Console in Program.cs , output to console duplicate cause you have two WriteTo.Console , One from appSetting.json , one from

builder.Services.AddLogging(logger =>
        {
            logger.ClearProviders();

            Log.Logger = new LoggerConfiguration()
               .ReadFrom.Configuration(builder.Configuration)
               .Enrich.FromLogContext()
               .CreateLogger();

            logger.AddSerilog();

            Log.Logger.Information("Serilog Initialized.");
        });


builder.Host.UseSerilog();

var app = builder.Build();
app.UseSerilogRequestLogging();
