utilising user secrets in .net 5 console app

I am building a simple console app to process a large CSV file. The SDK is version 5.0.202 and I am on Manjaro Linux.

CODE

using System;
using System.Text;
using TinyCsvParser;
using System.Linq;
using Microsoft.Extensions.Hosting;

namespace DrawsParser
{
    class Program
    {
        static void Main(string[] args)
        {
          var host = new HostBuilder()
            .ConfigureAppConfiguration((hostContext, builder) =>
            {
                if (hostContext.HostingEnvironment.IsDevelopment())
                {
                    builder.AddUserSecrets<Program>();
                }
            })
            .Build();

            host.Run();

            CsvParserOptions options = new CsvParserOptions(true, ',');
            CsvDrawResultMapping mapping = new CsvDrawResultMapping();
            CsvParser<DrawResult> parser = new CsvParser<DrawResult>(options, mapping);

            var results = parser
              .ReadFromFile(@"subset_game_data.csv", Encoding.UTF8)
              .ToList();

            foreach (var result in results)
            {
              var item = result.Result;
              string text = $"{item.Date.ToString()} | {item.State} | {item.Game} | {item.OriginalResult}";
              Console.WriteLine(text);
            }
        }
    }
}

PACKAGES

Project 'DrawsParser' has the following package references

When I run dotnet build . I get the following error:

/home/ryan/work/will/parser/DrawsParser/Program.cs(18,29): error CS1061: 'IConfigurationBuilder' does not contain a definition for 'AddUserSecrets' and no accessible extension method 'AddUserSecrets' accepting a first argument of type 'IConfigurationBuilder' could be found (are you missing a using directive or an assembly reference?) [/home/ryan/work/will/parser/DrawsParser/DrawsParser.csproj]

I'm not sure what I'm missing, I am actually following the official docs here.

Googling C# IConfigurationBuilder.AddUserSecrets leads to this docs page, which shows that the AddUserSecret extension method is defined in the Microsoft.Extensions.Configuration namespace, and checking your code you're missing the using Microsoft.Extensions.Configuration; directive
