Created Graphic with PictureFillSymbol don't show

Hi, I use  PictureFillSymbol Class Constructors PictureFillSymbol(Uri) \ PictureFillSymbol(Runtime) or PictureFillSymbol.CreateAsync(Stream imageStream)  to create a PictureFillSymbol then use it to create a Graphic and add it to a GraphicOverlay, but the Graphic doesn't show, below is my codes

The following code works for me, `T` here is just a png with BuildAction=Embedded Resource. `Forum` was my project namespace. I think the reason it didn't work for you is because you have a PictureFillSymbol for MapPoint geometry. Did you mean to use PictureMarkerSymbol then?
