DisplayInformation no longer has GetForCurrentView() that allows retrieving LogicalDpi. How can we obtain LogicalDpi with Win UI?

May you use Win32 High DPI functions, for example GetDpiForWindow?
@Xiaopo Yang - MSFT Thank you for the tip. Is there a straightforward way to do this with C#?
@Xiaopo Yang - MSFT Thank you. It works. I used the following code:
IntPtr hWnd = WinRT.Interop.WindowNative.GetWindowHandle(((App)Application.Current).MainWindow);
dpi = GetDpiForWindow(hWnd);
Could you turn your comment into an answer for me to accept?
Calling Win32 functions is a straightforward way as there is no such information in DisplayInformation class.
[DllImport("User32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
public static extern int GetDpiForWindow(IntPtr hwnd);
public f()
{
IntPtr hWnd = WinRT.Interop.WindowNative.GetWindowHandle(this);
int dpi = GetDpiForWindow(hWnd);
}
