研究方向
Investigate the drag and drop implementation in the WinUI 3 codebase, particularly in the XamlControls library. Review the comments in issue #7690 for any pointers on the elevated mode crash (0x8000FFFF). Focus on code paths that handle drag and drop in elevated processes, checking for integrity level checks or UIPI restrictions. Examine the error handling around the drag drop initialization and the use of Windows App SDK APIs.
