  • In ABP startup templates, logging is typically configured in Program.cs on purpose because the host needs a logger before the DI container and modules are built, so startup/bootstrapping errors are captured reliably (including failures that happen while reading configuration, building the app, running migrations, initializing modules, etc.). ABP also ships templates with Serilog pre-wired and a few “baseline” enrichers/sinks so you immediately get useful logs during development without extra setup.
  • That said, ABP does not prevent configuring logging from appsettings*.json. You can (and in production usually should) move almost all Serilog configuration into configuration files and let different environments override it using appsettings.Development.json, appsettings.Production.json, environment variables, etc.

  Concrete approach (template-friendly):

  1. Put Serilog settings into appsettings.json (and overrides into appsettings.{Environment}.json).
  2. In Program.cs, keep only the minimal bootstrap code and load Serilog from configuration:

  using Serilog;
  
     var builder = WebApplication.CreateBuilder(args);
  
     builder.Host.UseSerilog((context, services, loggerConfiguration) =>
     {
         loggerConfiguration
             .ReadFrom.Configuration(context.Configuration)   // <-- appsettings.json
             .ReadFrom.Services(services);                   // <-- DI-based enrichers if any
     });
  
     await builder.AddApplicationAsync<MyHttpApiHostModule>();
     var app = builder.Build();
     await app.InitializeApplicationAsync();
     await app.RunAsync();
  

  3. Use environment-specific configuration normally:
     • appsettings.Development.json -> verbose logs
     • appsettings.Production.json -> warning/error + production sinks (Elastic/AppInsights/etc.)

  What about “hardcoded minimum level” / WASM scenarios?

  • In Blazor WebAssembly, configuration and logging are constrained by the client-side hosting model; the template may set a default minimum level in code to ensure sane defaults and avoid shipping overly-verbose client logs unintentionally. You can still drive this via configuration, but you must ensure your WASM config files are actually loaded/selected per environment (WASM uses wwwroot/appsettings*.json).

  Links you referenced

  • ABP support thread (reachable): https://abp.io/support/questions/1496/ABPIO-WASM---Log-level-configuration
  • GitHub issue link you provided is not reachable from my URL check right now, so I’m not including it as a verified source.

  (If you want the “official ABP template” exact file/method name where Serilog is configured—e.g., a shared helper in *.Shared.Hosting—tell me your ABP version/template type and I can point to the exact implementation.)

  hi

  I agree with you, I will share a solution and update the code in our template projects.

  Thanks.

  hi

  Here is an example to use the log configuration with appsettings.json

  {
    "Serilog": {
      "MinimumLevel": {
        "Default": "Debug",
        "Override": {
          "Microsoft": "Information",
          "Microsoft.EntityFrameworkCore": "Warning"
        }
      },
      "WriteTo": [
        {
          "Name": "Async",
          "Args": {

              }
            ]
          }
        },
        {

          }
        }
      ],
      "Enrich": [ "FromLogContext" ]
    }
  }

          {
              Log.CloseAndFlush();
          }
      }

  Thanks.

  This is actually quite similar to the one we implemented now except for that we added rollover for log files and we named the "startup log" as startup.txt to keep it separate from the Serilog logging (which probably won't work for the earliest logging so still need that in ABP code probably, just as you did).. This seem to work fine even though we are still in early testing.
