Where should I put my IoC container (Composition Root)

Hi,

I'm going to use Ioc (TinyIoc) in a Xamarin.Forms project, but I'm not sure where I should put my Ioc container.
I'm thinking that I should place it in App class that is in the PCL that is created when a new Xamarin.Forms soulution is created. But I'm note sure if this is the right place.

Is it the right place?
