Typed HttpClient is not getting configuration from service registration

Describe the bug

I register a typed HttpClient with Startup and give it settings (BaseAddress and DefaultRequestHeaders). But these settings don't go to the HttpClient instance in the service. Instead, an HttpClient instance is instantiated with default settings.

To Reproduce

In Startup.cs ` public void ConfigureServices(IServiceCollection services) { var avazaBaseUrl = Configuration["Avaza:BaseUrl"]; var avazaAccessToken = Configuration["Avaza:PersonalAccessToken"]; services.AddHttpClient<IAvazaService, AvazaService>(client => { client.BaseAddress = new Uri(avazaBaseUrl); client.DefaultRequestHeaders.Add("Accept", "application/json"); client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", avazaAccessToken); });

        services.AddServices();
        services.AddControllers();
        services.AddSwaggerGen(c =>
        {
            c.SwaggerDoc("v1", new OpenApiInfo { Title = "WebApi", Version = "v1" });
        });
    }`

AvazaService.cs ` public class AvazaService : IAvazaService { private readonly HttpClient _httpClient;

    public AvazaService(HttpClient httpClient)
    {
        _httpClient = httpClient; // BaseAddress is null, DefaultRequestHeaders is empty
    }

    public async Task<Result<List<Timesheet>>> GetTimesheets()
    {
        var response = await _httpClient.GetAsync("api/Timesheet");

        if (!response.IsSuccessStatusCode)
            return Result.Failure<List<Timesheet>>($"Avaza returns: '{(int)response.StatusCode} {response.ReasonPhrase}' on request in GetTimesheets method");

        using var responseStream = await response.Content.ReadAsStreamAsync();
        var timesheetList = await JsonSerializer.DeserializeAsync<TimesheetList>(responseStream);

        return timesheetList.Timesheets;
    }
}`
