Logging using Serilog not creating logs in .NET Core 6 using 'Serilog.Sinks.File' option, while working in .NET Core 5

Question

I am using Serilog.Sinks.File in .NET Core 5 and it is working fine.

In .NET Core 5, I am using the subsequent configuration, startup.cs

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
    {
        Log.Logger = new LoggerConfiguration()
          .ReadFrom.Configuration(Configuration)
          .CreateLogger();
        loggerFactory.AddSerilog();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
    }

And appsettings.json file has

 "Serilog": {
"MinimumLevel": "Information",
"Override": {
  "Microsoft": "Warning"
},
"Using": [
  "Serilog.Sinks.File"
],
"WriteTo": [
  {
    "Name": "RollingFile",
    "Args": {
      "pathFormat": "C:\\logs\\myapi\\log-{Date}.txt"
    }
  }
]

}

The Nuget package used

<PackageReference Include="Serilog.Extensions.Logging" Version="3.1.0" />
<PackageReference Include="Serilog.Settings.Configuration" Version="3.3.0" />
<PackageReference Include="Serilog.Sinks.File" Version="5.0.0" />
<PackageReference Include="Serilog.Sinks.RollingFile" Version="3.3.0" />

Now, I am trying to achieve the same thing in .NET Core 6 application. I have kept the appsettings.json file as is it and used the code in Program.cs

var logger = new LoggerConfiguration()
.ReadFrom.Configuration(builder.Configuration)
  .Enrich.FromLogContext()
  .CreateLogger();

builder.Logging.ClearProviders();
builder.Logging.AddSerilog(logger);

But the application is not creating log files. What am I missing?

Try installing Serilog.AspNetCore and then add then change builder.Logging.AddSerilog(logger); to:

builder.Host.UseSerilog();
