_ViewImports.cshtml
_ViewImports.cshtml is a Razor file whose namespaces and directives are implicitly available to views and pages in its directory scope.
Pro ASP.NET Core 7, Tenth Edition
A Razor view imports file, typically _ViewImports.cshtml, declares namespaces and other directives available to Razor views in its scope.
- How it is used
- Shares namespace imports and tag-helper registration across MVC views or Razor Pages.
- How deep it goes
- Works through file placement, three directives, and their effects on type names and tag-helper availability; leaves tag-helper implementation to separate treatment.
- Examples
- Uses Views and Pages imports files, a shortened @model declaration, a partial-view tag helper, and project-defined view-component tag helpers.
- What you can do after
- Operate/configure it to shorten Razor type references and enable built-in or application tag helpers across the intended views or pages.

- How it is used
- Centralizes shared Razor directives and Tag Helper registrations across views, pages, partial views, and descendant folders.
- How deep it goes
- Defines supported directives, placement, hierarchy, and the boundary with _ViewStart.cshtml, but does not execute arbitrary C#.
- Examples
- Uses namespace imports, built-in Tag Helpers, and custom Tag Helper registration as concrete configuration examples.
- What you can do after
- Configure shared Razor namespaces and Tag Helpers without repeating directives in individual views.
