Description Cody Beyer (MSFT) 2014-10-05 23:38:43 UTC
Created attachment 8312 [details]

The following code fails when using an Unified API project:

		public override SizeF IntrinsicContentSize {
			get {
				return new SizeF (-1, -1);

The error states that the value must be CoreGraphics.CGSize. Changing the override to CGsize causes a compilation failure (defined below). Please see attached project as test case.

This appears to work (or at least launch) without the reported errors in the latest Xamarin.Mac alpha.

Please reopen if you run into more problems with this.
