// replace the contents of `pch.h` and `main.cpp` source code files with the code below.
// Be aware that the code below omits the details of obtaining a WinRT Direct3DSurface in
// the first segment of code, and obtaining a native DirectX surface in the second segment.
// The code shows only how to perform the conversion between the two.
