Out of interest, may I ask why? – Ingressive

Look here: msdn.microsoft.com/en-us/library/… – Heteromorphic

@Icemanind, the example is using httpwebrequest, which but i use httpclient in my application. – Calamint

@poke, strange, but i don't know why either, i just follow their api,but the api is using httpwebrequest – Calamint

Answer 1

In order to set the version you'll have to create an instance of HttpRequestMessage and set its Version property which you pass to HttpClient.SendAsync. You can use the helper HttpVersion utility class:

var requestMessage = new HttpRequestMessage 
{
    Version = HttpVersion.Version10
}; 

var client = new HttpClient();
var response = await client.SendAsync(requestMessage);

My UWP app has the HttpRequestMessage but it does not contain a proprty called 'Version'. Any thoughts? – Prosper

Answer 2

HTTP version is sent as a header in every request, so it is set in the message sent by System.Net.Http.HttpClient: see the ProtocolVersion property of the HttpWebRequest class.
