Description Philippe Monteil 2011-12-02 08:35:57 UTC
given the implementation of the CALayer. set Mask property:
public virtual CALayer Mask
 [Export ("setMask:", ArgumentSemantic.Retain)]
     if (value == null)
         throw new ArgumentNullException ("value");
     if (this.IsDirectBinding)
         Messaging.void_objc_msgSend_IntPtr (base.Handle, CALayer.selSetMask, value.Handle);
         Messaging.void_objc_msgSendSuper_IntPtr (base.SuperHandle, CALayer.selSetMask, value.Handle);
     this.__mt_Mask_var = value;

it seems impossible to reset the .Mask of a CALayer since trying to assign it a null value will cause an exception.

good catch
Comment 2 Sebastien Pouliot 2011-12-02 17:23:39 UTC
Fixed in maccore/master ae8db486911615f3d4b47af22d6aa72d57ac12df
It will be in future releases of 5.x and 5.0.x (but not the ones already branched and in progress)

Thanks for your quick answer: reporting bugs to Xamarin is a pleasure :-)
