Xamarin. XamlFilePathAttribute type not found?

Question

.NET

Hello colleagues!
There was a gap when building a Xamarin.Forms project. It gives an error that there is no XamlFilePathAttribute type.
What should I do? The project is clean.
Xamarin.Forms - 2.3.3.180
All other dependencies
Xamarin.Android.* - 23.3.0

PS: it's strange that even Google returns 45 links for xamarin XamlFilePathAttribute
PSS: damn, the file is wrong, but the meaning does not change.

Answer 1

Check if the project has a reference to the Xamarin.Forms.Xaml assembly (in Xamarin.Forms.Xaml.dll), if not, add it.
