c# - Xamarin.Forms.Platform.Android does not exist after Xamarin update from 2.5 to 3.5

I have updated my projects Xamarin.Forms NuGet package from version 2.5 to 3.5. After this update I got an error in my Android project saying:

The type or namespace name 'Android' does not exist in the namespace 'Xamarin.Forms.Platform' (are you missing an assembly reference?)

What I've tried so far:

  • Delete bin, obj folders
  • Close and Reopen solution
  • Clean and Rebuild solution
  • Reinstalling Xamarin Forms NuGet

@Jaymin is right. You must make sure that the version of the installed Xamarin.Android should be as same as the version that you have added to the current project.

For example, if you have installed v27.0.2.1 of Xamarin.Android, you can not upgrade your project to v28.0.0.1 only. You should upgrade the component(Xamarin.Android) which is installed with Visual Studio first.
