Some test text!
You should either call Dispose() or Destroy() but not both. Destroy() is a PDFTron API that closes the PDFDoc and releases resources, we would recommend you call this. On the other hand Dispose() is compiler generated and results in the destructor being called which in turn internally calls Destroy(). Please see the following description from the Microsoft documentation page:
"When you declare a public destructor, the compiler generates the code so that the ref class implements Platform::IDisposable and the destructor implements the Dispose method. Platform::IDisposable is the C++/CX projection of Windows::Foundation::IClosable. Never explicitly implement these interfaces."
