.net-core - ServicePoint 中的 CurrentConnections 返回零

Question

我试图在 ServicePoint 对象中查看 CurrentConnections 属性，但即使我使用任何公共 URI，它总是为我返回零；我正在使用 .NET Core。如果我遗漏了什么，有人可以告诉我吗？

这是我的测试用例的片段：

        IHttpClientFactory clientFactory = serviceProvider.GetService<IHttpClientFactory>();
        HttpClient client = clientFactory.CreateClient();
        var taskList = new List<Task<HttpResponseMessage>>();

        foreach (var item in Enumerable.Range(0, 1000))
        {
            taskList.Add(Task.Run(async () =>
            {
                HttpRequestMessage httpRequestMessage = new HttpRequestMessage(HttpMethod.Get, "https://www.bing.com/");
                ServicePoint servicePoint = ServicePointManager.FindServicePoint(httpRequestMessage.RequestUri); 
                if (servicePoint.CurrentConnections > 0)
                {
                    Assert.Fail($"Found non zero connection = {servicePoint.CurrentConnections}");
                }
                return await client.SendAsync(httpRequestMessage);
            }
            ));
        }
