HttpClient^ client = gcnew HttpClient();

HttpRequestMessage^ request = new HttpRequestMessage(HttpMethod::Get, "http://www.microsoft.com");
Console::WriteLine("Default HTTP request version is {0}", request.Version);

request.Version = HttpVersion.Version10;
Console::WriteLine("Request version after assignment is {0}", request.Version);

HttpResponseMessage^ response = client->Send(request);
Console::WriteLine("Response HTTP version {0}", response.Version);

// HttpClient lifecycle management best practices:
