How to view queries being issued?

[johnkwaters]

I went to see if I could log what queries are being sent, to diagnose an issue.
I see a hint about obsolete events, and to use a ClientEventHandler, but can't find how to do that. Where is this kind of documentation to be found?

Oh - I think it means to use the same handler that you use for authorization, its just the HttpClienHandler

    public class AuthorizationMessageHandler : HttpClientHandler
    {
        public AuthorizationMessageHandler(AuthenticationHeaderValue authorization)
        {
            Authorization = authorization;
        }
        public AuthenticationHeaderValue Authorization { get; set; }
        protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
        {
            if (Authorization != null)
                request.Headers.Authorization = Authorization;
            var res = await base.SendAsync(request, cancellationToken);
            if (!res.IsSuccessStatusCode)
            {
                Console.WriteLine(request.RequestUri.ToString());
            }
            return res;
        }
