全局捕获程序异常错误并写入asp.net Core 2.1 Web API中的文件

Question

I, am trying to create a global exception handling service for execution error not a http status error in asp.net core 2.1 web api and write to a file.

Tried few options like

services.AddMvc(config =>
            {
                config.Filters.Add(typeof(GlobalExceptionFilter));
            })
                .SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
                .AddSessionStateTempDataProvider();

Exception Class

public class GlobalExceptionFilter : IExceptionFilter
    {
        public void OnException(ExceptionContext context)
        {
            HttpStatusCode status = HttpStatusCode.InternalServerError;
            String message = String.Empty;

            var exceptionType = context.Exception.GetType();
            if (exceptionType == typeof(UnauthorizedAccessException))
            {
                message = "Unauthorized Access";
                status = HttpStatusCode.Unauthorized;
            }
            else if (exceptionType == typeof(NotImplementedException))
            {
                message = "A server error occurred.";
                status = HttpStatusCode.NotImplemented;
            }
            else if (exceptionType == typeof(MyAppException))
            {
                message = context.Exception.ToString();
                status = HttpStatusCode.InternalServerError;
            }
            else
            {
                message = context.Exception.Message;
                status = HttpStatusCode.NotFound;
            }
            context.ExceptionHandled = true;

            HttpResponse response = context.HttpContext.Response;
            response.StatusCode = (int)status;
            response.ContentType = "application/json";
            var err = message + " " + context.Exception.StackTrace;
            response.WriteAsync(err);
        }
    }

But it never coming to the errors.I tried with debugging but never hit the debugging code.
