c# - Using injected HttpClient from HttpClientFactory out of scope

Question

Consider this code

public class ScopedService {
    public readonly HttpClient client;
    public readonly MyHostedService hostedService;

    public ScopedService(HttpClient client, MyHostedService hostedService) {
        this.client = client;
        this.hostedService = hostedService;
    }

    public void LongAsyncOperationWeDontWantToWaitFor()
    {
        var httpTask = client.GetAsync("...");
        hostedService.SaveTaskForProcessSometimeInTheFuture(httpTask);
    }
}

I have a scoped service which makes an http call. I want the scope to close before the http call completes. If I created and disposed httpClient manually, then I'd do it out of scope myself. But since in this case the client is Dependency Injected, I have no control over when it's going to be disposed. Can there be a situation, that the context won't be able to close until the injected httpClient is disposed?

Answer 1

You could inject IHttpClientFactory and use it to create the HttpClient when you need it.
