            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.Development.json");

            //var configurationBuilder = new ConfigurationBuilder()
            // .Add(new JsonConfigurationSource { Path = "config.json", ReloadOnChange = true });

            IConfiguration config = configurationBuilder.Build();
            string connectionString = config[value];
            return connectionString;
        }
