Answer 1

Install xamarin.forms on all projects, in my case I was missing in the iOS project, it was enough to install the xamarin.forms nuget and everything worked normally. I hope it helps.

Answer 2

i finally found the solution. I opened android sdk manager and install Android 7.1 Nougat SDK (previously android 6.0 was installed). Then i right clicked solution and opened nuget manager. I selected Xamarin.forms package and choose the latest version of package and click install. I refreshed the package in all projects. Now everything works well.
