I changed the `MainContainerActivity` from a basic `FrameLayout` container to a `DrawerLayout` container using `NavigationView` and a `FrameLayout`. The project runs as expected while using MvvmCross 6.1.2. At this point I updated to MvvmCross 6.2.0-beta2 and the project no longer displays the first ViewModel.\r\n\r\nThe error is: \r\n> System.NullReferenceException: FrameLayout to show Fragment not found\r\n\r\n### Old (and correct) behavior\r\nThe first ViewModel is navigated to.\r\n\r\n### Current behavior\r\nA `System.NullReferenceException` is thrown during setup. The splash screen displays for a while, then the screen turns black instead of showing the first ViewModel.\r\n\r\n### Reproduction steps\r\nI've reproduce the problem [here](https://github.com/tbalcom/FrameLayoutNotFound). The project is currently referencing MvvmCross 6.2.0-beta2 from NuGet so you can observe the reported problem. You can edit the two CSPROJ files to downgrade back to 6.1.2, Clean, Rebuild and notice how the first ViewModel is displayed.\r\n### Configuration\r\n\r\n**Version:** 6.2.0-beta2\r\n\r\n**Platform:** \r\n- [ ] :iphone: iOS\r\n- [x] :robot: Android\r\n- [ ] :checkered_flag: WPF\r\n- [ ] :earth_americas: UWP\r\n- [ ] :apple: MacOS\r\n- [ ] :tv: tvOS\r\n- [ ] :monkey: Xamarin.Forms\r\n"}}
