Serilog configuration for non-logging Asp.Net Core 2.0.1

Question

I am trying to configure Serilog as my registrar in a multi-project solution using Asp.Net Core 2.0.1, EF 2.0.1 and MVC 6.

I created Serilog, mainly following the recommendations of this blog Configure Serilog Post

There is a json issue in this post that I fixed and is shown here.

Appsettings.json file

{
"ApplicationConfiguration": {
  "ConnectionStrings": {
    "DevelopmentConnection": "Server=(localdb)\\mssqllocaldb;Database=TestingConfigurationNetCoreTwo_Development;Trusted_Connection=True;MultipleActiveResultSets=true"      
  },      
  "ApplicationInfo": {
    "VersionNumber": "1.0.0",
    "Author": "Jimbo",
    "ApplicationName": "CustomTemplate",
    "CreatedOn": "November 20, 2017"
  },
  "Serilog": {
    "Using": [
      "Serilog.Sinks.RollingFile",
      "Serilog.Sinks.Async",
      "Serilog.Sinks.ApplicationInsights",
      "Serilog.Sinks.Console",
      "Serilog.Sinks.Seq"
    ],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning"
      }
    },
    "WriteTo": [
      {
        "Name": "Async",
        "Args": {
          "configure": [
            {
              "Name": "RollingFile",
              "Args": { "pathFormat": "Logs/log-{Date}.log" }
           }
          ]
        }
      }
    ],
    "Enrich": ["FromLogContext", "WithMachineName", "WithThreadId"],
    "Properties": {
      "Application": "CustomTemplate" 
    }
  }
}
}

I have a logger configuration in the main method of Program.cs

public static int Main(string[] args)
{
    var currentEnv = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT"); 

    var configuration = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("appsettings.json")
        .AddJsonFile($"appsettings.{currentEnv}.json", optional: true)
        .AddEnvironmentVariables()
        .Build();

    //Configure logger
    Log.Logger = new LoggerConfiguration()
        .ReadFrom.Configuration(configuration)
        //do this for now
        //TODO:figure out how to add to Serilog config in appsettings.json
        .WriteTo.Seq("http://localhost:5341")
        .CreateLogger();

    Log.Information("Logger created");

    try
    {
        Log.Information("Starting web host");
        BuildWebHost(args).Run();
        return 0;
    }
    catch (Exception ex)
    {
        Log.Fatal(ex, "Web Host terminated unexpectedly");
        return 1;
    }
    finally
    {
        Log.CloseAndFlush();
    }
    //BuildWebHost(args).Run();
}

public static IWebHost BuildWebHost(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>()
            .Build();

And in my launch method

services.AddLogging(loggingBuilder =>
            loggingBuilder.AddSerilog(dispose: true));
