Description Zhenya 2014-02-28 16:46:52 UTC
Can't always load NSImage by calling NSImage.ImageNamed. Steps:
1) Put Image.png to "Resources/Images" sub-folder.
2) Try loading the image by calling NSImage.ImageNamed("Resources/Images/Image.png") or NSImage.ImageNamed("Image.png").
Result: returned image is null
Expected: image is not null
Workaround: put Image.png to the Resources folder and load it by calling NSImage.ImageNamed("Image.png")
Comment 1 Aaron Bockover [MSFT] 2014-02-28 17:30:09 UTC
I believe this is the intended behavior. Xamarin.Mac doesn't do anything special here - it just calls the NSImage imageNamed: selector.

You can use methods on NSBundle to get the full path of an image inside the bundle and then load NSImage from a file. From what I understand, imageNamed: does not search subdirectories (this would likely be rather slow).

See for more details:
