Note that if you are using a Portable Class Library, HttpClient will not have PostAsJsonAsync method. To post a content as JSON using a Portable Class Library, you will have to do this:

HttpClient client = new HttpClient();
HttpContent contentPost = new StringContent(argsAsJson, Encoding.UTF8, 
"application/json");

await client.PostAsync(new Uri(wsUrl), contentPost).ContinueWith(
(postTask) => postTask.Result.EnsureSuccessStatusCode());
