我正在尝试在我的控制台应用程序中使用 .net core DI。当我写这样的东西时（下面的代码位于我的 Program.cs 中）：

    private static IServiceCollection ConfigureServices()
    {
            IConfigurationBuilder builder = new ConfigurationBuilder()
                                .SetBasePath(Directory.GetCurrentDirectory())

                Source = "Source",
                SecretHashPassword = "my-sercet-password",
                DataAccessTimeoutMs = 30_000
            };

            IOptions<ConfigurationOptions> options = Options.Create(configurationOptions);

            DatabaseTransactionManager databaseTransactionManager = new DatabaseTransactionManager();
            DbContext DbContext = new …
