✅ AddHttpClient and AddHostedService

I have a hosted service that I register with my DI as so
serviceCollection.AddHostedService<ExampleService>()

and everything works fine. However I now need this service to use it's own 
HttpClient
. That seemed like no issue, Just add 
serviceCollection.AddHttpClient<ExampleService>(x => x.Timeout = Timeout.InfiniteTimeSpan)
 and I should be good to go, or so I thought..

Everything resolved correctly and the program ran, except for the fact that the injected 
HttpClient
 did not in fact have infinite timeout. A quick breakpoint check later and i find that the configuration action isn't triggering, or from what I found online, that client isn't used at all and it's instead falling back to the standard 
HttpClient
 that 
AddHttpClient
 adds for everything that isn't the targeted type.

I found changing my hosted service declaration to 
serviceCollection.AddHostedService(provider => provider.GetRequiredService<ExampleService>())
 resolves these issues but I'm honestly kinda at a loss as to why I had to do this and feel like I must have done something wrong to need to do this. Could anyone enlighten me on the cause of this?
