//----- PART 4: THE BOWLING SCORE POST -----
//Sending data back using a REST-POST command
response = client.PostAsJsonAsync(UrlParameters, bsd).Result;
//NOTE on PostAsJsonAsync:
//HERE i am making a POST with the correct data shape, but the integers inside seems to be WRONG
//-as if my calculations are wrong.
//I believe the data shape is good, since i receive a 200 OK http response.
//After testing with EVERY single valueType that can contain a whole number, i still never received
//-any acknowledgement that my PostAsJsonAsync worked.
if (response.IsSuccessStatusCode) //Just like the GET, the POST can fail
{
HttpStatusCode status = response.StatusCode; //is always included. Saved here for later print.
//Note on ReadAsAsync:
//This call will enable you to read any data that the REST request may send back.
//Even if you expect only a single boolean to come back as a result:
//-you MUST be ready to grab an object that contain ALL the data in all the correct shapes.
//So here, an object containing ONLY a single boolean,
//will be able to catch the expected boolean result.
BowlingSuccess bs = response.Content.ReadAsAsync <BowlingSuccess>().Result;

//The boolean tells you if the bowling scores for the token-game are correctly calculated.

//3+ cases (3 where the server system visibly works):
//1. HTTP status 400 Bad Request. Means that the token does not correspond to a played game.
//2. HTTP status 200 OK + JSON { "success":false }. Means the token is recognized but the sums of points were badly calculated.
//3. HTTP status 200 OK + JSON { "success":true }. Means the token is recognized and the points are correctly calculated.
//+. HTTP errors of different kinds, and more.

//----- PART 5: THE CLEANUP -----
//Dispose once all HttpClient calls are complete. This is not necessary if the containing object will be disposed of; for example in this case the HttpClient instance will be disposed automatically when the application terminates so the following call is superfluous.
