What version of the Android SDK do you have installed? I'm using the support libraries from API 27, so you'll need this API version installed.

I needed to install Oreo 8.1 support.

I think the use of <AndroidUseLatestPlatformSdk>true</AndroidUseLatestPlatformSdk> is maybe not right - we should just pin to 8.1?

That just tells the compiler to use the latest version installed, and ideally should always be on latest platform rather than pinned to a version. The issue here was support libraries:

in the packages.config. For these NuGets to work you need to have at least 8.1 installed. The Xamarin team are working on autoupdating the installed SDK when you open a project, but not sure if that includes checking the support libraries. Will ping Pierce and ask him.
