HostingService not receiving HttpClient through DI about hosting HOT 4 CLOSED

from hosting.

services.AddHttpClient( c => { ... })

If you're doing this then you should be resolving PCSyncService from DI.

I think AddHostedService adds the service as a transient dependency. Without the AddHttpClient extension call my service receives the Ilogger through DI

from hosting.

If anyone has a similar issue in the future, I figured out how to solve the issue, but I do not know why.
I could not find the appropriate pattern for passing the HttpClient directly into an IHostedService. You must create another service interface, and pass that into the IHostedService. You must define this new Interface service first, then the HttpClient definition, then the HostedService binding.

public void ConfigureServices(IServiceCollection services)
        {
            services.AddTransient<IPeopleService, PeopleService>();
            services.AddHttpClient<IPeopleService,PeopleService>( c => {
                // configuration removed
            });
            services.AddHostedService<PCSyncService>();
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }
