UWP Object reference not set to an instance of an object.

Can someone help with this error ?

On the main navigation page icons are loaded but not on sub pages.

Object reference not set to an instance of an object.

The problem seems to be the control IconImage if i changed to IconLabel it worked.

I had this same error. In my case, specifying an explicit HeightRequest and WidthRequest solved the issue. My guess is that these properties do not have a default value and the image rendering creates an empty image object when the height and width are empty.

EDIT: In the PlatformExtensions.ToImageSourceAsync method, the SKSurface.Create method does not create a surface when the size is -1 (default when no Height or Width is specified).

using (var surface = SKSurface.Create(size, size, SKImageInfo.PlatformColorType, SKAlphaType.Premul))
