@Gaoyifei1011 buddy do you have some great function?

using WinRT;
var interop = GraphicsCaptureItem.As<IGraphicsCaptureItemInterop>();
var itemPointer = interop.CreateForWindow(hwnd,GraphicsCaptureItemGuid);
var item = GraphicsCaptureItem.FromAbi(itemPointer);
return item;

Please remember use GeneratedComInterface rather than ComImport to define IGraphicsCaptureItemInterop
