问题
Start with a fresh Android project in Visual Studio Professional 15.6.6, on Windows. Install Xamarin.Android.Support.Design from NuGet. Try to run on an Android 8 phone (mine is a BLU Vivo XL3). It probably won't run. It may (or may not) complain as follows:
"Android.Content.Res.Resources+NotFoundException: File res/drawable-xhdpi-v4/abc_ab_share_pack_mtrl_alpha9.png from xml type layout resource ID #0x7f020000
I also tried it on Visual Studio Professional 15.7.1. Same problem.
Any work arounds?
