How to specify context for Razor pages?

Question

ASP.NET

When creating any project with aps.net core mvc 5, whether pure or with angular, I see errors with context in razor views. How to fix it? At the same time, the directives themselves work. Connecting models works and everything is displayed correctly.

The error is purely cosmetic, but very unpleasant, because. these mistakes are many, many. 20 pieces per page.
