I've got a Xamarin.Forms project in which I'm trying to use an Entry and set its FontFamily in XAML. I keep getting a XAML exception about the FontFamily property not existing. I'm working in Xamarin Studio, but a coworker in Visual Studio can't find any reference to the property even in the binary (confirmed v1.5) that we're referencing. The same problem exists for HorizontalTextAlignment and FontSize.
The docs for FontFamily specify that it's available in 1.5, and we're definitely at 1.5. But it's just not there. Are we missing something obvious, or are the docs wrong?
