How curl maps to C# (HttpClient)

→Uses HttpClient and HttpRequestMessage with top-level statements (.NET 6+).
→Content-Type moves onto the StringContent: .NET throws if you put it on the request headers.
→Reuse one HttpClient for your whole app (or IHttpClientFactory) — creating one per request exhausts sockets.

Frequently asked

Why can't I add Content-Type to HttpClient request headers?

In .NET, Content-Type is a content header. Set it through the HttpContent, e.g. new StringContent(body, Encoding.UTF8, "application/json"), which is what the converter does.

Is it OK to create a new HttpClient for every call?

No. Each instance holds its own connections, and creating many can exhaust sockets. Keep a single instance or use IHttpClientFactory.
