Configure custom Column Options for Serilog Sinks MsSqlServer in AppSettings.json is not working

问题

I'm trying to determine if it's possible to configure the column options for serilog sink mssqlserver in the appsettings.json file for an ASP.Net Core 3 project.

besides not filling the custom columns, the database is also created in the standard way without these column, so I added them by hand. This could point to a configuration issue?

The SQL to create the table

    CREATE TABLE [dbo].[logtable](
        [Id] [int] IDENTITY(1,1) NOT NULL,
        [Message] [nvarchar](max) NULL,
        [MessageTemplate] [nvarchar](max) NULL,
        [Level] [nvarchar](128) NULL,
        [TimeStamp] [datetimeoffset](7) NOT NULL,
        [Exception] [nvarchar](max) NULL,
        [Properties] [xml] NULL,
        [LogEvent] [nvarchar](max) NULL,
        [Controller_Name] [varchar](500) NULL,
        [Method_Name] [varchar](500) NULL,
        [StackTrace] [varchar](500) NULL
    )

I create and configure the logger in the Program.cs file.


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

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

I can build the configuration file from the appsettings.json file, which contains a Serilog node with information for which connection string and table to use.

"Serilog": {
    "Using": [ "Serilog.Sinks.MSSqlServer" ],
    "MinimumLevel": "Information",
    "WriteTo": [
      {
        "Name": "MSSqlServer",
        "Args": {
          "connectionString": "Data Source=SWPC159; Initial Catalog=master;Trusted_Connection=True;", // connection String
          "tableName": "logtable",
          "columnOptionsSection": {
            "disableTriggers": true,
            "clusteredColumnstoreIndex": false,
            "addStandardColumns": [ "LogEvent" ],
            "removeStandardColumns": [ "MessageTemplate", "Properties" ],
            "additionalColumns": [
              {
                "ColumnName": "Controller_Name",
                "DataType": "varchar",
                "AllowNull": true,
                "DataLength": 500
              },
              {
                "ColumnName": "Method_Name",
                "DataType": "varchar",
                "AllowNull": true,
                "DataLength": 500
              },
              {
                "ColumnName": "StackTrace",
                "DataType": "varchar",
                "AllowNull": true,
                "DataLength": 500
              }
            ]
          }
        }
      }
    ]
  }

Replacing configuartion with hosting context,solve the issues

public static IWebHost BuildWebHost(string[] args)
        {
            return WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>()
            .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration.ReadFrom
            .Configuration(hostingContext.Configuration))
            .Build();
        }
