Why this? Same error type with both Xamarin Studio and Visual Studio. Tried reinstalling but nothing resolved. I am new to xamarin and xamarin studio.
Did code nothing this is the code generated by IDE when creating a new project.
From the second screenshot you post, the question is that you haven't installed the relative nugets.
According to the error, you can try to install Nugets xamarin.android.support.design and Xamarin.Essentials.
RunningVisual Studio 2019
Xamarin Studio 5.9.6
Not resolved even if I updated all the NuGet Packages.
