在 .net 5 控制台应用程序中利用用户机密

我正在构建一个简单的控制台应用程序来处理大型 CSV 文件。 SDK版本5.0.202我使用的是 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);
            }
        }
    }
}

当我跑步时dotnet build .我收到以下错误：

/home/ryan/work/will/parser/DrawsParser/Program.cs(18,29)：错误CS1061：“IConfigurationBuilder”不包含“AddUserSecrets”的定义，并且没有可访问的扩展方法“AddUserSecrets”接受第一个参数可以找到类型“IConfigurationBuilder”（您是否缺少 using 指令或程序集引用？）[/home/ryan/work/will/parser/DrawsParser/DrawsParser.csproj]

我不确定我错过了什么，我实际上正在遵循.

谷歌搜索C# IConfigurationBuilder.AddUserSecrets导致this https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.configuration.usersecretsconfigurationextensions.addusersecrets?view=dotnet-plat-ext-5.0文档页面，其中显示AddUserSecret扩展方法定义在Microsoft.Extensions.Configuration命名空间，并检查您缺少的代码using Microsoft.Extensions.Configuration;指示
