DataTransferManager cannot share in elevated mode #6216
Description
Describe the bug
DataTransferManager cannot share in elevated mode
-----------------------------
DataTransferManager 不能在提权模式下进行分享
As shown in the figure, when running in administrator mode and performing a share operation through DataTransferManager, although the share panel can be opened via the IDataTransferManagerInterop interface, the DataRequested event of DataTransferManager does not trigger properly, causing file sharing to fail. It is hoped that future versions of Windows can fix this bug, or that the Windows App SDK can provide an appropriate alternative solution.
-----------------------------
如图所示，应用在管理员模式下，通过 DataTransferManager 进行分享操作时，虽然可以通过 IDataTransferManagerInterop 接口打开分享面板，但是 DataTransferManager 的 DataRequested 事件并不能正常触发，故文件分享失败。希望未来 Windows 能修复一下这个 bug，或 Windows App SDK 能提供相应的替代方案。
