I have a typed HttpClient and (let's say) another service/class that uses IHttpClientFactory to get a HttpClient instance.
To register IHttpClientFactory, I inject it as services.AddHttpClient(). And to register typed clients, I go with services.AddHttpClient<MyTypedClient>
My question is, do you think there will be a problem if I use both of the use cases. Any impact on HttpMessageHandler pool?
Thanks, Cem.
Simply, no. You can use whatever you want. IHttpClientFactory handles the collection of HttpMessageHandler instances. When you inject a typed client, what's actually happening is that IHttpClientFactory is invoked, and new HttpClient instance is created, and its handler is set to the either an already created HttpMessageHandler instance or a new instance.
In other words, it's mostly syntactic sugar. IHttpClientFactory is invoked in either case, and it always creates a new HttpClient instance, setting the handler to one that's tracking, based on name. A "typed" client is really just a "named" client, with the type as the name, and all clients are in effect "named" because it's all being stored in a ConcurrentDictionary, where the name is the key.
