Error passing CoreWindow as function parameter - c++

Question

I am new to UWP and WinRT, I already knew DirectX11 and Win32 and I am quite interested in learning UWP and WinRT.
DXMainResources is a class to use Diret3D and Direct2D, and the most important thing when creating resources is the window (CoreWindow), however, when passing the window as a function parameter, many errors appear such as:
C2065 error 'bEnableDepthStencilBuffer': undeclared identifier
Error C2065 'window': undeclared identifier
Error C2065 'window_': undeclared identifier
Faced with these errors, remove the CoreWindow window parameter and the program compiles, but the window as a parameter is necessary, since I need its height and width to create the swap chain and the texture for the depth stencil view.
Is there a way to pass the window as a parameter?
I'm using DirectX 11.3 interfaces and the WinRT version I'm using is 2.0.201026.4

Refer to the Important in the document, please add the following #include statement and using statement, then try to compile your project.
#include <winrt/Windows.UI.Core.h>
using namespace winrt::Windows::UI::Core;
