Imported @page directive should log a diagnostic.

[NTaylorMullen]

Today if you import an @page directive you end up with Razor thinking a view is a "page" but then MVC doesn't detect that. We should log a diagnostic indicating that imported @page directives are invalid.

Couldn't we make it so that @page does not get imported?

@pranavkm You could but then you'd have silent errors in the system. I'd rather let it be imported and indicate that it's an error when a user attempts to use that imported view.
