C# 11: HttpClient Not Reusing Connections in .NET 7 Causing High Latency
Quick question that's been bugging me - I'm experiencing an scenario with `HttpClient` where it seems not to be reusing connections as expected, leading to significantly increased latency in my API calls... I am using .NET 7 and C# 11. Despite following best practices, my application is creating new connections for each request. Here’s a simplified version of my code: ```csharp public class ApiService { private readonly HttpClient _httpClient; public ApiService(HttpClient httpClient) { _httpClient = httpClient; } public async Task<string> GetDataAsync(string url) { var response = await _httpClient.GetAsync(url); response.EnsureSuccessStatusCode(); return await response.Content.ReadAsStringAsync(); } } ``` In my `Startup.cs`, I register `HttpClient` like this: ```csharp services.AddHttpClient<ApiService>(); ``` However, when I monitor the network traffic using Wireshark, I notice that multiple TCP connections are being established for requests to the same host, which is unusual. This leads to higher latency, as connections are being opened and closed frequently. I have also tried using `HttpClientFactory` to manage the lifecycle of `HttpClient`, but the scenario continues. I am not setting the `HttpClientHandler` explicitly, so it should use the default settings. Is there something I might be missing in the configuration, or is there a known scenario with connection pooling in .NET 7? Any insights or solutions would be greatly appreciated. My development environment is Ubuntu.
