        /// Configures the app configuration using the given builder.
        /// </summary>
        /// <param name="builder">The functions configuration builder.</param>
        public override void ConfigureAppConfiguration(IFunctionsConfigurationBuilder builder)
        {
        }

        /// <summary>

                   .SetBasePath(Environment.CurrentDirectory)
                   .AddEnvironmentVariables();

            var location = string.IsNullOrEmpty(Environment.GetEnvironmentVariable(ConfigurationConstants.LOCATION))

                    : Environment.GetEnvironmentVariable(ConfigurationConstants.ASPNETCORE_ENVIRONMENT);

            configurationBuilder.AddJsonFile($"{ConfigurationConstants.APPSETTINGS}.{environment}{location}.json", optional: true, reloadOnChange: true);

#if DEBUG
