[Bug]: HttpClient named client with the same name overwrite ConfigureHttpClient BaseAddress

[squadwuschel]

Describe the bug 🐞

I am using named clients to Authorize my client access, and here I have multiple APIs using the same Named client.
Now I am creating multiple Refit Clients for multiple Interfaces (multiple different API URLs) and all use the same Named client to authenticate.

When I Inject the API Client Interfaces into my services/controller, from all Interfaces the BaseAdress is the last baseAddress from my Registered Refit Clients.

Step to reproduce

Here you can see my setup:

  services.AddHttpClient("GitHubClient", client =>
        {
            client.BaseAddress = new Uri("https://api.github.com/");
            client.DefaultRequestHeaders.Add("Accept", "application/json");
            // Weitere Konfigurationen hier ...
        });
       
  services
       .AddRefitClient(typeof(IArticlesApi), null, $"GitHubClient")
       .ConfigureHttpClient(c => c.BaseAddress = new Uri("https://myArticlesApi.com"));

  services
       .AddRefitClient(typeof(IContentApi), null, $"GitHubClient")
       .ConfigureHttpClient(c => c.BaseAddress = new Uri("https://myContentApi.com"));

Expected behavior

when I now inject the "IContentApi" and the "IArticlesApi" into an Controller or Service/Provider
the Client.BaseAdress on both injected Interfaces is "https://myContentApi.com" => the last registered c.BaseAddress.
That seems to be wrong I would say, because, when I Use multiple different named clients, then each BaseAddress is like expected.

This is expected behavior. You're just reconfiguring the same IHttpClientFactory, and the actual clients aren't instantiated until injection time, and the factory produces different instances for each injection site, they are not all the same reference to the same client.
