.Net Core - Azure Application Insights not showing exceptions

Where and how to put azure application insights exceptions on global level in .net core project? I am having app insights installed and I can follow telemetry in azure, but exceptions are missing for failed requests.

One approach would be to create custom middleware which would catch the error and send the exception to AppInsights.

using System;
using System.Threading.Tasks;
using Microsoft.ApplicationInsights;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Http;

namespace Middleware
{
    public static class ApplicationBuilderExtensions
    {
        public static IApplicationBuilder UseHttpException(this IApplicationBuilder application)
        {
            return application.UseMiddleware<HttpExceptionMiddleware>();
        }
    }

    public class HttpExceptionMiddleware
    {
        private readonly RequestDelegate _next;

        public HttpExceptionMiddleware(RequestDelegate next)
        {
            _next = next;
        }

        public async Task Invoke(HttpContext context)
        {
            try
            {
                await _next.Invoke(context);
            }
            catch (Exception ex)
            {
                var telemetryClient = new TelemetryClient();
                telemetryClient.TrackException(ex);

                //handle response codes and other operations here
            }
        }
    }
}

Then, register the middleware in the Startup's Configure method:

app.UseHttpException();
