    private class LoggingStrategy : BuilderStrategy
    {
        public LoggingStrategy( ILogger logger )

            _logger = logger;
        }

        #region BuilderStrategy
        public override void PreBuildUp( IBuilderContext context )
        {
            _logger.Log( $"Resolving {context.BuildKey.Type} for {context.OriginalBuildKey.Type}" );
        }

        #region private
        private readonly ILogger _logger;
        #endregion
    }
    #endregion
}
