I seems Xamarin.Forms don't support Mono.Android 8.0? Upgrading Android support libraries to 26.x.x (API level 26 = 8.0 Oreo) because Xamarin.forms seems to have a strict dependency to 25.x.x.
When trying to upgrade Xamarin.Android.Support.Design to 22.214.171.124 the following error occurs:
"Version conflict detected for Xamarin.Android.Support.Compat. Reference the package directly from the project to resolve this issue.
TestApp.Android -> Xamarin.Android.Support.Design 126.96.36.199 -> Xamarin.Android.Support.Compat (= 188.8.131.52)
TestApp.Android -> Xamarin.Android.Support.v4 184.108.40.206 -> Xamarin.Android.Support.Compat (= 220.127.116.11)."
And also, if you look at the dependencies for the Xamarin.Forms nuget package, MonoAndroid 8.0 isn't even listed. Why is that? And what can I do to use API level 26 support libraries in XF?
