How do I manage singleton Regex initialization in Scoped service ?

both IMaskingOperator and IMaskingPolicy is scoped service. I have regex pattern used with value of scoped service. In this case for performance, how can I ensure the regex is initialized only once ?

    public class DefaultMaskingOperator : IMaskingOperator
    {
        private Regex regex;
        public DefaultMaskingOperator(IMaskingPolicy policy)
        {
            string pattern = $"...{policy.MaskKeyList}...";
            regex = new Regex(pattern,RegexOptions.Compiled);
        }

        public string MaskWithRegex(string input)
        {
            string output = string.Empty;
            var matches = regex.Matches(input);
            //...
            return output;
        }
    }

    public class DefaultMaskingOperator : IMaskingOperator
    {
        private Regex regex;
        public DefaultMaskingOperator(IMaskingPolicy policy)
        {
            string pattern = $"...{policy.MaskKeyList}...";
            regex = new Regex(pattern,RegexOptions.Compiled);
        }

        public string MaskWithRegex(string input)
        {
            string output = string.Empty;
            var matches = regex.Matches(input);
            //...
            return output;
        }
    }

❔ Evaluating C# Expressions At Runtime

I am looking alternative ways to evaluate C# expression at runtime. I have used Roslyn Scripting API CSharpScript.RunAsync but as mentioned github issues, its not designed to be called continuously because it keep creating new assembly in memory and not unloaded, causes memory leak (https://github.com/dotnet/roslyn/issues/41722)

❔ ✅ How to implement pool tracking in concurrent list ?

I am trying to add tracking to my logging service. (Web API project) Once track count is matched, I disbound the ConcurrentBag and send list to logger service. I need review in this approach where I don't want to lose log data since this method is called in every request.

private readonly ConcurrentBag<object> _objects = new ConcurrentBag<object>();

public void Log<T>(T data) where T : class
{
    try
    {
        _objects.Add(data);
        if (_objects.Count >= _logOption.TrackCount)
        {
            Task.Factory.StartNew(async () =>
            {
                var dataList = new List<object>();
                for (int i = 0; i < _logOption.TrackCount; i++)
                {
                    if (_objects.TryTake(out object item))

                    {
                        dataList.Add(item);
                    }
                }
                await SendToKafkaApi(dataList);
            });
        }
    }
    catch (Exception ex)
    {
        LogOnFile(ex);
    }
}

✅ ILGenerator Object Mapper Property Set

Hey, I have following object mapper for non nested class types https://www.paste.org/124478. There are some use cases where return value of Convert method is not re-assigned to destination type, therefore the passed TTgt target argument is not updated since the reference properties are not set directly, therefore I added "ref" wrapper but I don't want to change existing codes to "ref" version. How can I update the existing ILGenerator that maps the properties explicitly, meaning it will update the argument target parameter as reference
