Answer 1

Hello,​

Welcome to our Microsoft Q&A platform!

Hi, what's the version of the VS on your pc? Someone faced the similar issue with Visual Studio Pro 16.8.1, the solution is to update the Xamarin.Forms package to the lastest stable version. Case link:https://developercommunity.visualstudio.com/comments/1257384/view.html

Try updating the nuget to the lastest statable version, then clean and rebuild.

Best Regards,
