Hello,
Welcome to our Microsoft Q&A platform!
Hi, @Prasanth Kumar Did you update the nuget packages after updating the VS? Visual Studio may reference different apis by default with VS 2017. Try to update the nuget packages to the lastest stable version on both the shared project and each platform project. Then clean and rebuild. For Android, the lastest Xamarin.Forms 5.0 requires the TargetFramework to be Adnroid 10 or above and AndroidX is now the default on Android. If you defined some cusotm code in Android project, please change the related namespaces to AndroidX.*
