    /// 
    ///

    {
        /// 

        /// 
        /// 
        public sealed class ConfigurationManagerAppSettings

            /// 

            /// 
            /// 
            internal ConfigurationManagerAppSettings() { }

            /// 

            /// 
            /// 
            ///

        /// 

        /// 
        /// 
        public static IConfiguration? TheConfiguration { get; set; }

        /// 

        /// 
        /// 
        public static readonly ConfigurationManagerAppSettings AppSettings = new ConfigurationManagerAppSettings();
    }

and below code:

public class Startup
    {
        public Startup(IConfiguration configuration) {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services) {
            ConfigurationManager.TheConfiguration = Configuration;
