Serilog Sink to ASPNET Core Logging

Question

I wish I could process my code using Serilog and Microsoft.Extensions.Logging (ILogger). And let them both be configured the same way, so they write the same "sinks". I have an ASPNET Core application with running logs and some dependent libraries using Serilog that I would like to get from the log output (in the same place as the ASPNET Core application).

I know that there is a nuget package for using Serilog registration with ASPNET Core applications. However this is a private extension

(WebAppBuilder).UseSerilog()

There is an opportunity to completely replace the existing ILoggerFactory version with serilog, and this will stop my ASPNET log. That would be fine if I could just plug in the serilog configuration so that it works like the original ASPNET Core engine. However, Serilog.Settings.Configuration does not seem to copy the configuration to Serilog.

I am also worried that they cannot use the shared resource, what if I use other libraries that use, say, NLog, how do I integrate this into the same logging infrastructure?

Is it possible to configure Serilog in the same way as Microsoft.Extensions.Logging? And if so, how is this achieved?

In yours Program.csyou will have this (after loading yours IConfigurationRoot):

Log.Logger = new LoggerConfiguration()
    .ReadFrom.Configuration(configuration)
    .WriteTo.Console()
    .CreateLogger();

"" , , appsettings.json.

appsettings.json , :

{
    "Serilog": {
        "MinimumLevel": {
            "Default": "Information",
            "Override": {
                "Microsoft": "Warning",
                "System": "Error"
            }
        },
        "WriteTo": [{
            "Name": "Seq",
            "Args": {
                "serverUrl": "http://localhost:5341"
            }
        }],
        "Enrich": ["FromLogContext"],
        "Properties": {
            "Application": "MyApplication"
        }
    }
}

Serilog.Log:

Log.Information("JSON example {@Json}", json);

Microsoft.Extensions.Logging.ILogger:

logger.LogInformation("JSON example {@Json}", json);
