[Bug] Updating to latest packages breaks the VS 2017 build

[omghb]

Description

After updating the following packages of my Xamarin Forms App resulted in a broken build:

• Xamarin.Android.Support.* from 28.0.0.1 to 28.0.0.3
• Xamarin.Forms from 4.2.0.709249 to 4.2.0.815419
• Xamarin.Essentials from 1.3.0 to 1.3.1

The build worked in VS 2017 with the previous versions on all platforms.

When the scope is different from the defining assembly, it usually means that the type is forwarded. ---> Mono.Cecil.ResolutionException: Failed to resolve System.Collections.Generic.Stack`1
