Because WNDCLASSEXW is not defined. So define it above 
RegisterClassExW.

struct WNDCLASSEXW {
   UINT      cbSize = WNDCLASSEXW.sizeof;
   UINT      style;
   WNDPROC   lpfnWndProc;
   int       cbClsExtra;
   int       cbWndExtra;
   HINSTANCE hInstance;
   HICON     hIcon;
   HCURSOR   hCursor;
   HBRUSH    hbrBackground;
   LPCTSTR   lpszMenuName;
   LPCTSTR   lpszClassName;
   HICON     hIconSm;
}
