Description Anton 2015-03-23 04:49:13 UTC
MTLRegion.Create2D (actually, all overloads) throwing EntryPointNotFoundException

Enviroment:
Xamarin Studio 5.8 (build 442) Mono 3.12.1
Xamarin.iOS 8.8.0.2
iPhone 6+ with iOS 8.2
Comment 1 Sebastien Pouliot 2015-03-23 10:25:50 UTC
There's no overload for Create2D, but I think you mean that Create1D and 3D do not work either.
Comment 2 Rolf Bjarne Kvinge [MSFT] 2015-03-23 10:29:40 UTC
Fixed.

This is implemented as inline methods in the iOS headers, and thus does not have a native method to P/Invoke.

Until the fix comes out you can easily work around it by using this code:

	public static MTLRegion Create2D (nint x, nint y, nint width, nint height)
	{
		var region = new MTLRegion ();
		region.Origin.X = x;
		region.Origin.Y = y;
		region.Origin.Z = 0;
		region.Size.Width = width;
		region.Size.Height = height;
		region.Size.Depth = 1;
		return region;
	}
