 public class Startup     {         public Startup(IHostingEnvironment env)         {             Configuration = new ConfigurationBuilder()                 .SetBasePath(env.ContentRootPath)                 .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)                 .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true, reloadOnChange: true)                   .AddEnvironmentVariables()                 .Build();         }         public IConfiguration Configuration { get; }
