Does Xamerin have something like WindowsFormsHost? Need Unity3D inside Xamerin.Forms

I want to run separate process inside a frame in Xamerin.Forms app. Something like this can be done with WPF using WindowsFormsHost or HwndHost.

Again I am talking about a separate process, I understand that the 2 processes would have to interact with some cross process way etc. My only question is can I run a separate process inside a frame inside a Xamerin.Forms app
