Error 0x87DD0005 when implementing Xbox Live services

I just got done adding Xbox support code to my project, and have run into at least two issues.
The first involves save data sync which is working just fine, however when the game reads the user's login data on Windows it behaves as if login has not been completed - no gamertag is displayed in the corner, and the login provider throws error 0x87DD0005 regardless of the number of retry attempts.
Execution of the code is just fine on Xbox - only Windows seems to be affected by this. I'm also targeting the creator's showcase initially (or at least until I can get to where I'm ready for another run at ID#Xbox) so achievements and the like aren't a concern right now.
The following is the code I'm using (and in no particular order):
public void doStartup()
{
getData(-1);
for (int i = 0; i <= 5; i++)
{
getData(i);
}
ContentViewport.Source = new Uri("ms-appx-web:///logo.html");
}
public async void getData(int savefileId)
{
var users = await Windows.System.User.FindAllAsync();
string c_saveBlobName = "Advent";
//string c_saveContainerDisplayName = "GameSave";
string c_saveContainerName = "file" + savefileId;
if (savefileId == -1) c_saveContainerName = "config";
if (savefileId == 0) c_saveContainerName = "global";
GameSaveProvider gameSaveProvider;
GameSaveProviderGetResult gameSaveTask = await GameSaveProvider.GetForUserAsync(users[0], "00000000-0000-0000-0000-00006d0be05f");
//Parameters
//Windows.System.User user
//string SCID
if (gameSaveTask.Status == GameSaveErrorStatus.Ok)
{
gameSaveProvider = gameSaveTask.Value;
}
else
{
return;
//throw new Exception("Game Save Provider Initialization failed");;
}
//Now you have a GameSaveProvider
//Next you need to call CreateContainer to get a GameSaveContainer
GameSaveContainer gameSaveContainer = gameSaveProvider.CreateContainer(c_saveContainerName);
//Parameter
//string name (name of the GameSaveContainer Created)
//form an array of strings containing the blob names you would like to read.
string[] blobsToRead = new string[] { c_saveBlobName };
// GetAsync allocates a new Dictionary to hold the retrieved data. You can also use ReadAsync
// to provide your own preallocated Dictionary.
GameSaveBlobGetResult result = await gameSaveContainer.GetAsync(blobsToRead);
string loadedData = "";
//Check status to make sure data was read from the container
if (result.Status == GameSaveErrorStatus.Ok)
{
//prepare a buffer to receive blob
IBuffer loadedBuffer;
//retrieve the named blob from the GetAsync result, place it in loaded buffer.
result.Value.TryGetValue(c_saveBlobName, out loadedBuffer);
if (loadedBuffer == null)
{
//throw new Exception(String.Format("Didn't find expected blob \"{0}\" in the loaded data.", c_saveBlobName));
}
DataReader reader = DataReader.FromBuffer(loadedBuffer);
loadedData = reader.ReadString(loadedBuffer.Length);
if (savefileId == -1)
{
try
{
System.IO.File.WriteAllText(ApplicationData.Current.TemporaryFolder.Path + "\\config.json", loadedData);
}
catch { }
}
else if (savefileId == 0)
{
try
{
System.IO.File.WriteAllText(ApplicationData.Current.TemporaryFolder.Path + "\\global.json", loadedData);
}
catch { }
}
else
{
try
{
System.IO.File.WriteAllText(ApplicationData.Current.TemporaryFolder.Path + "\\file" + savefileId + ".json", loadedData);
}
catch { }
}
}
}
public async void InitializeXboxGamer()
{
try
{
XboxLiveUser user = new XboxLiveUser();
if (user.IsSignedIn == false)
{
SignInResult result = await user.SignInSilentlyAsync(Window.Current.Dispatcher);
if (result.Status == SignInStatus.UserInteractionRequired)
{
result = await user.SignInAsync(Window.Current.Dispatcher);
}
}
System.IO.File.WriteAllText(ApplicationData.Current.TemporaryFolder.Path + "\\curUser.txt", user.Gamertag);
doStartup();
}
catch (Exception ex)
{
// TODO: log an error here
}
}

I finally managed to figure out why the Xbox was working but Windows was not: it was a platform support issue. In the game's creator's dashboard for Xbox Live there's a settings window that allows the support of the game to be determined. Because I originally had separate builds for Xbox and Windows, only the Xbox support item was checked, so I went ahead and also checked off for Desktop support. After saving the changes, I resubmitted with the new configuration and now it works properly.

Rapidly Increasing Memory usage C#

I have code that basically opens a webpage + .ts file from a link and repeats it, but the problem is it increases memory usage each time and never removes the old data. After 2 Hours it uses more than 2GB.
Any ideas on how I can fix this issue?
I'm using "Leaf.Xnet" Library for requests and this is how I create my threads:
new Thread(new ThreadStart(WebHelper.Check)).Start();
Main code:
public static void Check()
{
HttpRequest request = null;
while (Form1.isRuning)
{
Application.DoEvents();
try
{
request = new HttpRequest();
if (!ProxyManager.updating)
{
switch (ProxyManager.curProxyType)
{
case ProxyManager.proxyType.http:
request.Proxy = HttpProxyClient.Parse(ProxyManager.NextProxy(ProxyManager.proxyType.http));
break;
case ProxyManager.proxyType.socks4:
request.Proxy = Socks4ProxyClient.Parse(ProxyManager.NextProxy(ProxyManager.proxyType.socks4));
break;
case ProxyManager.proxyType.socks5:
request.Proxy = Socks5ProxyClient.Parse(ProxyManager.NextProxy(ProxyManager.proxyType.socks5));
break;
}
}
else
{
Thread.Sleep(2000);
Check();
}
request.UserAgentRandomize();
request.AddHeader(HttpHeader.Referer, "https://somesite.com");
request.KeepAlive = true;
request.ConnectTimeout = Form1.timeOut;
request.Reconnect = true;
string html = request.Get(Form1.link, null).ToString();
string auth = html.Substring(",[{\"src\":\"", "\"");
string sign = html.Substring("144p.apt?wmsAuthSign=", "\"");
if (auth != null && sign != null)
{
string auth2 = "";
foreach (char item in auth)
{
if (item != '\\')
auth2 += item;
}
auth = auth2;
string cdn = auth.Substring("https://", ".");
string id = auth.Substring("video/", "-");
if (cdn != null && id != null)
{
Random rnd = new Random();
request.Get(auth);
Form1.sended++;
WriteStat();
}
html = null;
auth = null;
auth2 = null;
sign = null;
}
}
catch (HttpException)
{
Check();
}
catch (ProxyException)
{
Check();
}
}
}

I am not entirely sure if this will fix your problem but for each thread that you start, you pretty much call an infinite number of executions of Check(). Since Check contains a while loop, the thread will run whatever is in side forever anyway, and now you're calling the method again on top of it. This means that everything that was created in the scope of the Check method will not be garbage collected and will increase your memory.
Replace all calls to Check() with continue which will stop the execution in the while loop and start over.
Also, consider not using Threads, but instead use Tasks.
Also you do not dispose your HttpRequest.

Problem with passing constantly reading serial buffer data to another class

Long story short. ;
I have a class named Scope. And this class contains all logic for scope operations etc. It also starts backround thread that constantly read serial port data (in my case events was unreliable):
Thread BackgroundReader = new Thread(ReadBuffer);
BackgroundReader.IsBackground = true;
BackgroundReader.Start();
private void ReadBuffer()
{
SerialPort.DiscardInBuffer();
while (!_stopCapture)
{
int bufferSize = SerialPort.BytesToRead;
byte[] buffer = new byte[bufferSize];
if(bufferSize > 5)
{
SerialPort.Read(buffer, 0, bufferSize);
Port_DataReceivedEvent(buffer, null);
}
Thread.Sleep(_readDelay);
}
CurrentBuffer = null;
}
In Scope class there is a public field named Buffer
public byte[] Buffer
{
get
{
return CurrentBuffer;
}
}
And here is event fired while there is new data readed
private void Port_DataReceivedEvent(object sender, EventArgs e)
{
//populate buffer
Info(sender, null);
CurrentBuffer = ((byte[])sender);
foreach(byte data in CurrentBuffer)
{
DataBuffer.Enqueue(data);
}
if (DataBuffer.Count() > _recordLength)
{
GenerateFrame(DataBuffer.ToArray());
DataBuffer.Clear(); ;
}
}
To make code more manageable, I splitted it in several classes. One of this classes is for searching specific data pattern in current stream and create specific object from this data. This code works in way that send to serial port specific command and expect return frame. If reponse is not received or not ok, send is performed again and again until correct response arrives or there will be timeout. Response is expected to be in current buffer. Those strange string manipulation is for debug purposes.
public class GetAcknowledgedFrame
{
byte[] WritedData;
string lastEx;
string stringData;
public DataFrame WriteAcknowledged(Type SendType, Type ReturnType, JyeScope scope)
{
var stopwatch = new Stopwatch();
stopwatch.Restart();
while (stopwatch.ElapsedMilliseconds < scope.TimeoutTime)
{
try
{
if (SendType == typeof(GetParameters))
{
WriteFrame(new ScopeControlFrames.GetParameters(), scope.SerialPort);
}
else if(SendType == typeof(GetConfig))
{
WriteFrame(new ScopeControlFrames.GetConfig(), scope.SerialPort);
}
else if (SendType == typeof(EnterUSBScopeMode))
{
WriteFrame(new ScopeControlFrames.EnterUSBScopeMode(), scope.SerialPort);
}
return ReturnFrame(ReturnType, scope.Buffer, scope.TimeoutTime);
}
catch (InvalidDataFrameException ex)
{
lastEx = ex.Message;
System.Threading.Thread.Sleep(10);
}
}
stringData = "";
foreach (var data in scope.Buffer)
{
stringData += data + ",";
}
stringData.Remove(stringData.Length - 1);
throw new TimeoutException($"Timeout while waiting for frame acknowledge: " + SendType.ToString() + ", " + ReturnType.ToString() + Environment.NewLine+ "Add. err: "+lastEx);
}
private DataFrame ReturnFrame(Type FrameType, byte[] buffer, int timeoutTime)
{
if (FrameType == typeof(DataFrames.DSO068.CurrConfigDataFrame))
{
DataFrames.DSO068.CurrConfigDataFrame CurrConfig = new DataFrames.DSO068.CurrConfigDataFrame(buffer);
return CurrConfig;
}
else if (FrameType == typeof(DataFrames.DSO112.CurrConfigDataFrame))
{
DataFrames.DSO112.CurrConfigDataFrame CurrParam = new DataFrames.DSO112.CurrConfigDataFrame(buffer);
return CurrParam;
}
else if (FrameType == typeof(CurrParamDataFrame))
{
CurrParamDataFrame CurrParam = new CurrParamDataFrame(buffer);
return CurrParam;
}
else if (FrameType == typeof(DataBlockDataFrame))
{
DataBlockDataFrame CurrData = new DataBlockDataFrame(buffer);
return CurrData;
}
else if (FrameType == typeof(DataSampleDataFrame))
{
DataSampleDataFrame CurrData = new DataSampleDataFrame(buffer);
return CurrData;
}
else if (FrameType == typeof(ScopeControlFrames.ScopeReady))
{
ScopeControlFrames.ScopeReady ready = new ScopeControlFrames.ScopeReady(buffer);
return ready;
}
else
{
throw new InvalidOperationException("Wrong object type");
}
}
private bool WriteFrame(DataFrame frame, IStreamResource port)
{
WritedData = frame.Data;
port.Write(frame.Data, 0, frame.Data.Count());
return true;
}
}
From main class (and main thread) I call method in this class, for example:
var Ready = (ScopeControlFrames.ScopeReady)new GetAcknowledgedFrame().WriteAcknowledged
(typeof(ScopeControlFrames.EnterUSBScopeMode), typeof(ScopeControlFrames.ScopeReady), this);
The problem is when I pass "this" object (that has thread working in background) to my helper class. It seems like helper class not see changing data in this object. The problem started when I separate code of my helper class from main class.
My questions:
- I know that object are passed by reference, that means I think that when object is dynamically changing its state (in this case data buffer should changing while new data is received) all classes that has reference to this object are also seeing this changes. Maybe I'm missing something?
- I tried passing array (by ref), arrays are also reference types. But this not help me at all. Maybe I'm missing something?
I tried changing this class to static, it not helped.
Many thanks for help.

The code below;
Info(sender, null);
CurrentBuffer = ((byte[])sender);
is creating a new reference variable called CurrentBuffer. Any other code holding a reference 'pointer' to the CurrentBuffer value prior to this line of code will not get the new value of CurrentBuffer when its reset.

Multithreaded c# console app to scrape data from sites

I have written an app that goes through our own properties and scraps the data. To make sure I don't run through the same URLs, I am using a MySQL database to store the URL, flag it once its processed. All this was being done in a single thread and it's fine if I had only few thousand entries. But I have few hundred thousand entries that I need to parse so I need to make changes in the code (I am newbie in multithreading in general). I found an example and was trying to copy the style but doesn't seem to work. Anyone know what the issue is with the following code?
EDIT: Sorry didn't mean to make people guess the issue but was stupid of me to include the exception. Here is the exception
"System.InValidCastException: 'Specified cast is not valid.'"
When I start the process it collects the URLs from the database and then never hits DoWork method

All this code is based from Best multi-thread approach for multiple web requests this link. Can someone tell me how to get this approach running?

I think the problem is in the way you're creating your tasks:
new Task(id => new Worker().DoWork((int)id, item.Url, token), item.Url, token)
This Task constructor overload expected Action<object> delegate. That means id will be typed as object and you need to cast it back to something useful first.
Parameters
action
Type: System.Action<Object>
The delegate that represents the code to execute in the task.
state
Type: System.Object
An object representing data to be used by the action.
cancellationToken
Type: System.Threading.CancellationToken
-The CancellationToken that that the new task will observe.
You decided to cast it to int by calling (int)id, but you're passing item.Url as the object itself. I can't tell you 100% what the type of Url is but I don't expect Url-named property to be of type int.

Based on what #MarcinJuraszek said I just went back to my code and added an int as I couldn't find another way to resolve it. Here is the change I made
int i=0
foreach (var item in items)
{
urls.Add(item.Url);
WaitingTasks.Enqueue(new Task(id => new Worker().DoWork((string)id, item.Url, token), item.Url, token));
i++;
}

ReliableCollections Service Fabric: Statemanager's GetOrAddAsync() returns invalid queue with different names

I have two reliable queues and they are being accessed by two guest executables and each of them access their own. Sometimes the function I use to access them doesn't update the reliable queue object in the function and the wrong request is sent to the wrong guest executable.
What happens is that the clientId is passed by the guest executable to this function in the Get request. Let us say that there are two clientId(s) called T1 and T2.
What happens is that the guest executable (client) T2 at times gets the request that was meant for T1. Even though I tried line by line debugging the parameters passed to this function are correct.
Here is my API's POST that is passed a json to be added to the queue for the clients to receive from the GET
[HttpPost("MarketInfo")]
public JObject GetMarketInfo([FromBody] JObject jObject)
{
List<JToken> clients = jObject.GetValue("clients").ToList();
string json;
JObject response = new JObject();
JArray jsonArray = new JArray();
try
{
foreach (JToken client in clients)
{
var id = Guid.NewGuid();
json = "{'name':'MarketInfo','id':'" + id.ToString() + "','mtClientId':'" + terminal["name"].ToString() + "','parameters':{'symbol':'" + terminal["symbol"].ToString() + "','property':24}}";
bool result = _requestsCollectionHandler.CreateRequestForClient(JObject.Parse(json));
JObject clientResponse = new JObject();
if (result==true)
{
clientResponse["name"] = client["name"].ToString();
clientResponse["guid"] = id.ToString();
jsonArray.Add(clientResponse);
}
else
{
clientResponse["name"] = terminal.Children()["name"].ToString();
clientResponse["guid"] = "ERROR";
jsonArray.Add(terminalResponse);
}
}
response["clients"] = jsonArray;
return response;
}
catch (Exception e)
{
Debug.Write(e.Message);
return null;
}
}
This is the json that we pass to this API
{"clients":[{"name":"T1","symbol":"SomeInfo"},{"name":"T2","symbol":"SomeInfo"}]}
The problem is always with the clients object that is passed first.
Before I explain further let me also share the code for the client's HttpGet
[HttpGet("{clientId}")]
public string Get([FromRoute] string clientId)
{
try
{
string request = _requestsCollectionHandler.GetRequestJsonFromQueue(clientId);
return request;
}
catch(Exception e)
{
return e.Message;
}
}
This is the function that creates an object that is to be added by another function in the reliable queue
public bool CreateRequestForClient(JObject jObject)
{
try
{
this._jObject = new JObject(jObject);
CreateKey();
AddToRequestToQueueAsync();
return true;
}
catch (Exception e)
{
Debug.Write(e.Message);
_exceptionMessage = e.Message;
return false;
}
}
private void CreateKey()
{
dynamic data = JObject.Parse(_jObject.ToString(Newtonsoft.Json.Formatting.None));
string name = data.name;
string id = data.id;
string clientId = data.clientId;
_key.id = id;
_key.name = name;
_key.clientId = clientId;
//key.timestamp = GetTimestamp();
_key.timestamp = GetTimestamp();
_key.requestJson = _jObject.ToString(Newtonsoft.Json.Formatting.None);
}
_key is a private variable in class a custom class
This is the function in my class of request handler that adds the requests to the queue
private void AddToRequestToQueueAsync()
{
var transaction = this._stateManager.CreateTransaction();
CancellationToken cancellationToken
= new CancellationToken(false);
try
{
string queue = _key.clientId;
IReliableConcurrentQueue<TerminalResponseKey> reliableQueue =
_stateManager.GetOrAddAsync<IReliableConcurrentQueue<TerminalResponseKey>>(queue).Result;
transaction = this._stateManager.CreateTransaction();
if (reliableQueue!=null)
{
long count = reliableQueue.Count;
reliableQueue.EnqueueAsync(transaction, _key);
count = reliableQueue.Count;
transaction.CommitAsync().Wait();
}
else
{
transaction.Abort();
}
}
catch
{
transaction.Abort();
throw;
}
}
This is function that is used by the client
public string GetRequestJsonFromQueue(string clientId)
{
string queue = clientId;
try
{
IReliableConcurrentQueue<TerminalResponseKey> reliableQueue =
this._stateManager.GetOrAddAsync<IReliableConcurrentQueue<TerminalResponseKey>>(queue).Result;
if(reliableQueue != null)
{
ConditionalValue<TerminalResponseKey> key =
reliableQueue.TryDequeueAsync(transaction).Result;
if(key.HasValue)
{
string request = key.Value.requestJson;
transaction.CommitAsync().Wait();
return request;
}
}
else
{
transaction.Abort();
}
return "NO QUEUE";
}
catch (Exception e)
{
Debug.WriteLine(e);
transaction.Abort();
return e.InnerException.Message;
}
}
As far as I have found out I think my problem is in this function above. Because I don't know how the client T2 or client T1 gets another client's queue because the parameters determining the queue are their IDs and are totally unique.
These Ids are also passed correctly to this:
IReliableConcurrentQueue<TerminalResponseKey> reliableQueue =
this._stateManager.GetOrAddAsync<IReliableConcurrentQueue<TerminalResponseKey>>(queue).Result;
As you can see that we have queue=clientId
I have tried adding proper timespans but it was of no use as there is no exception thrown for OperationTimedOut. Furthermore since I am new to ServiceFabric I maybe totally doing anything wrong.
PS: Sorry for maybe a lot of jumbled up and confused code and question AND SOME OF THE INFORMATION IS OBFUSCATED DUE TO CONFIDENTIALITY BUT NOTHING OBSTRUCTING THE UNDERSTANDING OF THIS IS HIDDEN (I Hope not an issue)
I hope this is not an issue maybe an error I am overlooking at my side

When you put the request in the queue, in AddToRequestToQueueAsync(), the name of the queue is set from _key.terminalId (and I don't see where you assign it), but when you read from it, in GetRequestJsonFromQueue(), the clientId
is used as the queue name.
