Tracking Environment configuration change

We have this code to read configuration from Environment variables. Is there a way I can track any change in environment variable?

public static IHostBuilder UseHostAppConfiguration(this IHostBuilder hostBuilder)
        {
            hostBuilder.ConfigureHostConfiguration(configHost =>
            {
        	  string basePath = AppContext.BaseDirectory;
                configHost.SetBasePath(basePath);
                configHost.AddJsonFile("hostsettings.json", optional: true);
                configHost.AddEnvironmentVariables();

                // add multiple environments support to generic host from asp.net core
                configHost.AddEnvironmentVariables(prefix: "ASPNETCORE_");
            });
  }

AFAIK there isn’t a way to monitor for environment variables changes (other than polling).

This is correct. In general Environment Variables aren’t considered something that’s likely to change (they can’t be changed from outside the process for example).

Closing as this isn’t something we intend to add.
