I got the same error after updating Xamarin.forms from 4.8 to 5.0.

When you create a Xamarin.forms solution, you will get a Xamarin.forms project and an Android(iOS, UWP) project.

I guess this error happens because I only updated the Xamarin.forms package in the Xamarin.forms project.

You also need to update your Xamarin.forms package in the Android(iOS, UWP) project.

Hope it helps.

This was what caused the error for me: mixed versions. I had updated the packages in Android but not for iOS. Doing an update at the solution level (called "Consolidate") solved the error.

I was dealing with this problem after migrating a PCL project to .Net Standart and indeed the cause was different versions of Xamarin.Forms, you saved my life!
