using Microsoft.Extensions.Hosting;
public class Program{    public static void Main(string[] args)    {        CreateHostBuilder(args).Build().Run();    }
    public static IHostBuilder CreateHostBuilder(string[] args)    {            return Host.CreateDefaultBuilder(args)                   .ConfigureSecretStore((context, config, builder) =>                   {                       // Uses the environment variables from the environment block associated with the current process.                       builder.AddEnvironmentVariables();
                       // Uses the environment variables stored or retrieved from the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment key in the Windows operating system registry.                       builder.AddEnvironmentVariables(EnvironmentVariableTarget.Machine);
                       // Uses the environment variables starting with 'ARCUS_' from the environment block associated with the current process.                       builder.AddEnvironmentVariables(prefix: "ARCUS_");
                       // Uses the environment variables, using underscores and capitals for secret name structure.                       // Example - When looking up Queue.Name it will be changed to ARCUS_QUEUE_NAME.                       builder.AddEnvironmentVariables(mutateSecretName: name => $"ARCUS_{name.Replace(".", "_").ToUpper()}");
                       // Providing an unique name to this secret provider so it can be looked up later.                       // See: "Retrieve a specific secret provider from the secret store"                       builder.AddEnvironmentVariables(..., name: "Configuration");                   })                   .ConfigureWebHostDefaults(webBuilder => webBuilder.UseStartup<Startup>());    }}
