Created a CustomControl, gave it an ImageSource DP called "SkinSource". Dragged it onto the main page (ie MainPage.xaml). I then select a JPG/PNG from the pulldown for this DP, it inserts the images as followed:

"Assets/MyDir/My.jpg"

when it should be

"AssemblyName;component/Assets/MyDir/My.jpg"

If i then take the same Control and put it into a sub-view, and then do the above, it does the correct AssemblyName;Component approach.

Irrespective, the MainPage.xaml should respect the URI pathing, given most newbies won't pick up on this easily.

I've seen a lot of confusion in the forums around this whole concept and I suspect this will unlock a lot of confusion if the above were to be implemented.
