Providing thread-safe singleton HttpClients

Why?

'Long-lived' HttpClient static/singleton instances is the recommended use pattern in .NET. Avoid the unnecessary overhead of IHttpClientFactory, and definitely avoid creating a new HttpClient instance per request.

HttpClientCache provides a thread-safe singleton HttpClient instance per key via dependency injection. HttpClients are created lazily, and disposed on application shutdown (or manually if you want).
