Refit with HttpClientFactory creates many connections

[RizwanSharp]

Hello,

I have a straightforward demo Web API using Refit where I am using the following code to register ISomeApi refit contract:

builder.Services.AddRefitClient<ISomeApi>().ConfigureHttpClient(client =>
{
    client.BaseAddress = new Uri("https://microsoft.com");
});

My controller is injected with an ISomeApi instance that I use inside a controller action.

The problem is every time, I hit that controller action, I see a new connection established (using netstat -ano -b | findstr ), I see over 50 connections after hitting the endpoint about 50+ times.

My expectation using HttpClientFactory was that it reuses connections so I registered a named Client and injected IHttpClientFactory in the code:

builder.Services.AddHttpClient("someApi", httpClient =>
{
      httpClient.BaseAddress = new Uri("https://microsoft.com")
});

When I used the injected httpClientFactory to create and use an HttpClient, no matter how many times I hit that endpoint, I only see one connection.

Can somebody explain if I am doing something wrong, or is it a bug?

Thank You,
Rizwan

This is not an issue as I had HttpResponseMessage returning from the refit method and I wasn't disposing it. Changing the return type to string or any other type resolved the issue.

[Get("")]
Task <string> GetAsync();
vs
[Get("")]
Task <HttpResponseMessage> GetAsync();
