Adding File logging into .net Core 2.0 application

Will be making use of Serilog to log for our application. To get started we need the following Nuget packages.

• Serilog.AspNetCore
• Serilog.Settings.Configuration
• Serilog.Sinks.Console
• Serilog.Sinks.RollingFile

StartUp.cs

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Serilog;

namespace MyBlog
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(configuration).CreateLogger(); // <-- add for logging

            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }


        public void ConfigureServices(IServiceCollection services)
        {

            services.AddLogging(loggingBuilder => loggingBuilder.AddSerilog(dispose: true)); //<-- added for logging
           
            services.AddMvc();
        }


        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {

            loggerFactory.AddSerilog(); // <--add for logger


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

}

Program.css

using Microsoft.AspNetCore.Hosting;
using Serilog;

namespace Umbai.HotRecharge
{
    public class Program
    {
        public static void Main(string[] args)
        {
            BuildWebHost(args).Run();
        }

        public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .UseSerilog() // <-- Add for logging
                .Build();
    }

}

Appsetting.json

"Serilog": {
    "Using": [ "Serilog.Sinks.Console" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      { "Name": "Console" },
      {
        "Name": "RollingFile",
        "Args": {
          "pathFormat": "logs\\log-{Date}.txt",
          "outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] {Message}{NewLine}{Exception}"
        }
      }
    ],
    "Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
    "Properties": {
      "Application": "My Application"
    }
  }

and thus it, you can now use it in your code by passing in the logger into your code using dependency injection.
