.NET Core 7: Global Error Handling

Hi,

I'm trying to do global handling in a .NET Core 7 project. However, when I import the IExceptionHandler interface, using System.Web.Http.ExceptionHandling adds this class. There is a method to this too. But later, when I try to add it to program.cs, it does not see this class. What is the problem here? Also can you make an example? Can you help me.

using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using System.Web.Http.ExceptionHandling;

namespace FlightProject.Application.Exceptions
{
    public class GlobalExceptionHandler : IExceptionHandler
    {
        private readonly ILogger<GlobalExceptionHandler> _logger;

        public GlobalExceptionHandler(ILogger<GlobalExceptionHandler> logger)
        {
            _logger = logger;
        }

        public Task HandleAsync(ExceptionHandlerContext context, CancellationToken cancellationToken)
        {
            throw new NotImplementedException();
        }

        public async ValueTask<bool> TryHandleAsync(HttpContext httpContext, Exception exception, CancellationToken cancellationToken)
        {
            string errorMessage = $"Bir hata oluştu. Hata mesajı :  {exception.Message}";
            _logger.LogError(exception, errorMessage);

            httpContext.Response.StatusCode = StatusCodes.Status500InternalServerError;
            await httpContext.Response.WriteAsJsonAsync(new
            {
                Title = "Server Error",
                Status = httpContext.Response.StatusCode,
                Message = errorMessage
            });

            return true;
        }

    }
}

Program.cs

builder.Services.AddExceptionHandler<GlobalExceptionHandler>();
