I'm not sure if it is a bug, or if I'm doing something wrong, but it seems that ViewCellRenderer has stopped working in all versions of xamarin forms after 1.3.5.6335. My entire project relies on custom viewcells, so that is kind of a problem. I made a simple project to reproduce the problem. It works with 1.3.5.6335 but not with 1.3.5.6337 or 1.4.0.6341 where it fails with error:
System.Diagnostics.Debugger.Mono_UnhandledException (ex={System.NullReferenceException: Object reference not set to an instance of an object
