HttpClientFactory
HttpClientFactory is a factory for HttpClient instances in the .NET platform that centralizes the creation and lifetime management of HttpClient and HttpMessageHandler objects. It was designed to address common issues with manual HttpClient usage, such as socket exhaustion from improper disposal and stale DNS resolution due to long-lived underlying handlers. By pooling handlers and coordinating lifetimes, the factory enables the use of long-lived HttpClient instances without resource leaks and with up-to-date DNS information.
In ASP.NET Core and other .NET applications, HttpClientFactory is provided through the dependency injection system (Microsoft.Extensions.Http).
Benefits of using HttpClientFactory include centralized and reusable configuration, improved resource efficiency through handler pooling, and
