I have developed a Forms app and the app pages derive from ContentPage. However the functionality is now required to be built into an existing (non-Forms) Xamarin app, the "host" app. The host app is trying to display the app in a window but it is expecting a ContentView based app (tested with a simple "HelloWorld" Forms app) and not a ContentPage-based one. Is it in anyway possible to put my ContentPage-based app in the ContentView? Or should it be possible to open a ContentPage-based app in a fullscreen window from within the non-Forms app?
