如何在.NET Core控制台应用程序中使用Microsoft.Extensions.DependencyInjection？

我基本上像这样使用它：

安装nuget Microsoft.Extensions.DependencyInjection

然后在Program.cs中

using Microsoft.Extensions.DependencyInjection;

 public class Program
    {
        public static void Main(string[] args)
        {

            var services = new ServiceCollection()
                .AddSingleton<WhateverType>(new WhateverType());

            var serviceProvider = services.BuildServiceProvider();


            serviceProvider.GetService<WhateverType>().DoWork();
        }
    }
