Controls not appearing with Windows Insider

I created a HyperV VM with Windows Insider 18290, Windows Insider SDK 18298 and Visual Studio 2017 Community Edition. When running the code on that none of the controls display, just the text that indicate what the controls are. What am I doing wrong?

Build fails with: class template optional is only available with C++17 or later.

I'm on 17673, with VS 15.9 Preview 3 and RS5 SDK.

The build fails with:

Crash when exiting app with debugger attached.

When running this sample with VS2017 or VS2019 debugger attached, I am experiencing a crash when exiting the app, as long as I have interacted with any of the UWP controls attached to the sample. We need guidance on how to properly clean up and shutdown when using XAML Islands.
