HttpClient Get and Post

HttpClient httpClientGet = new HttpClient();
Task<string> httpClientGetResult = httpClientGet.GetStringAsync(@"https://localhost:7037/api/Values");
Console.WriteLine(httpClientGetResult.GetAwaiter().GetResult());

HttpClient httpClientPost = new HttpClient();

Task<HttpResponseMessage> httpResponseMessage = httpClientPost.PostAsync(@"https://localhost:7037/api/Values"
    , new StringContent(@"""string Test"""
        , Encoding.UTF8
        , "text/json"));

Task<string> httpClientPostResult = httpResponseMessage.Result.Content.ReadAsStringAsync();
Console.WriteLine(httpClientPostResult.Result);

UPDATE: Just a short notice, correct way to use HttpClient synchronously:

var task = Task.Run(() => myHttpClient.GetAsync(someUrl)); 
task.Wait();
var response = task.Result;
