C# Tip: use IHttpClientFactory to generate HttpClient instances
The problem with HttpClient When you create lots of HttpClient instances, you may incur Socket Exhaustion. This happens because sockets are a finite resource, and they are not released exactly when you 'Dispose' them, but a bit later. So, when you create lots of clients, you may terminate the available sockets.
he purpose of IHttpClientFactory is to solve that issue with HttpMessageHandler.
An interesting feature of IHttpClientFactory is that you can customize it with some general configurations that will be applied to all the HttpClient instances generated in a certain way. For instance, you can define HTTP Headers, Base URL, and other properties in a single point, and have those properties applied everywhere.
