I am creating an app that draws shapes on canvas and those shapes are recognized as letters using https://github.com/phatware/WritePadSDK sdk for writing pad. but the problem is that this api code works fine when it is used in windows 8.1 project but when the same code is used in windows 10 universal app it produces error when i debugged the code. Code of xaml is given bellow
<Canvas Background="WhiteSmoke" Name="InkCanvas" PointerPressed="OnCanvasPointerPressed" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" PointerReleased="OnCanvasPointerReleased" PointerCaptureLost="OnCanvasPointerCaptureLost" PointerExited="InkCanvas_OnPointerExited" PointerMoved="OnCanvasPointerMoved" LostFocus="InkCanvas_LostFocus">
and the code which is recognizes the shape using sdk is given bellow which is executed on PointerReleased event of Canvas:-
var resultValue = recognizerShared.RecognizeStrokes(InkCanvas.Children.ToList(), false);
and when i inspected the method given in sdk i.e. RecognizeStrokes which does the recolonization i got error when i did debugging
As this code works fine in windows 8.1 project i think it can be something todo with windows 10 universal app problem
Excelption details is given bellow:-

Please help me to solve the problem above.
