As mentioned in

https://docs.microsoft.com/en-us/dotnet/architecture/microservices/implement-resilient-applications/use-httpclientfactory-to-implement-resilient-http-requests#issues-with-the-original-httpclient-class-available-in-net-core

The

has sockets exhaustion and DNS changes issues, which are addressed by IHttpClientFactory. It also provide extensions for adding resiliency to the application.
