Type of issue

Other (describe below)

Description

here say:

Using this constructor is equivalent to calling the HttpClient(new HttpClientHandler(), true) constructor.

but there say

Starting in .NET Core 2.1, the implementation of the HttpClientHandler class was changed to be based on the cross-platform HTTP protocol stack used by the System.Net.Http.SocketsHttpHandler class. Prior to .NET Core 2.1, the HttpClientHandler class used older HTTP protocol stacks (WinHttpHandler on Windows and CurlHandler, an internal class implemented on top of Linux's native libcurl component, on Linux).

and github runtime soure show:

public HttpClient() : this(new HttpClientHandler())

There's nothing conflicting about it, HttpClientHandler now uses SocketsHttpHandler as it's default handler:
https://github.com/dotnet/runtime/blob/4f82fe7a0eca5efba3bb87425b42ecaa3e9e9516/src/libraries/System.Net.Http/src/System/Net/Http/HttpClientHandler.cs#L22

In the past, it used WinHttpHandler / CurlHandler and you had to opt-in in SocketsHttpHandler.

@ManickaP
I read it like public HttpClient() : this(new SocketsHttpHandler ()). So isn't that what happened?
i use DelegatingHandler need a InnerHandler
I'm not sure who I should use

[ManickaP]

new HttpClient() is the same as new HttpClient(new HttpClientHandler()) which is the same as new HttpClient(new HttpClientHandler(new SocketsHttpHandler())).

I don't understand your other questions, please be more specific and/or share a code snippet.

[zms9110750]

ContainerBuilder builder = new ContainerBuilder();
builder.RegisterInstance(pipeline);
builder.Register<HttpMessageHandler>(_ => new ResilienceHandler(pipeline) { InnerHandler = new HttpClientHandler() });
builder.RegisterType<HttpClient>();

just use ResilienceHandler

[ManickaP]

I'm sorry, but what is actual question here?

[zms9110750]

i not sure i should use
InnerHandler = new HttpClientHandler()or InnerHandler = new SocketsHttpHandler ()
But there's no problem now.
