ASP.NET Core Razor Pages & Views 2

Question 1

What is the primary purpose of a Razor Layout page in ASP.NET Core?

Accepted Answer

To define shared HTML structure like headers and footers reused across multiple views

Answer

Layout pages define a common HTML structure (headers, footers, navigation) that multiple content views can share, eliminating repetition.

Question 2

Which file is conventionally used to set a default layout for all Razor views in a folder and its subfolders?

Accepted Answer

_ViewStart.cshtml

Answer

_ViewStart.cshtml executes before any view in the same folder and is typically used to set the Layout property globally.

Question 3

What does calling @RenderBody() inside a Razor Layout page accomplish?

Accepted Answer

It inserts the content page's HTML at that location within the layout

Answer

@RenderBody() is the placeholder in a layout where the child content page's unique HTML markup is rendered.

Question 4

How do named sections work between a layout page and a content page?

Accepted Answer

@RenderSection() in the layout renders a section defined with @section in the content page

Answer

@RenderSection('Name') in the layout defines where the section renders; @section Name { } in the content page supplies the HTML for that section.

Question 5

What is the purpose of _ViewImports.cshtml in an ASP.NET Core project?

Accepted Answer

To share @using directives and @addTagHelper registrations across all views in a folder

Answer

_ViewImports.cshtml provides shared @using, @addTagHelper, and other directives to all views in its folder and subfolders, avoiding repetition.
