from Groove Music: 

this shadow is not solidcolorbrush, it is generated from that image. 
using a Path with its Fill property set to a effect brush is a solution, but any other solution available?
> Have you tried -WinUIVersuin 2.6? No, please fix it.
__weak在mrc下可用
因为throw了异常
新手强答: 可以手动实现property的setter,然后在其中mutablecopy。
