I thought I’d mention this given there is no nuget/compiled .dll for tvoOS: I’ve just uploaded a new sample to Xamarin’s sample gallery which serves as an empty template for tvOS.
I’m sure with Xamarin Studio 6 being fully released soon, tvOS will join the rest of the platforms as a distributed .dll, but in the meantime this should get people started:
