In the Model-View-Controller (MVC) pattern, the view handles the app's data presentation and user interaction. A view is an HTML template with embedded Razor markup. Razor markup is code that interacts with HTML markup to produce a webpage that's sent to the client.

Base View

Theme base view is Views/Shared/Layout.cshtml, in this file we are connecting all global styles and scripts. Each layout template should be wrapped with this view.

Content will be rendered in the place of @RenderBody() .

Specifying a Layout

Razor views have a Layout property. Individual views specify a layout by setting this property.

@{
  Layout = "~/Views/Shared/_Layout.cshtml";
}

The layout specified can use a full path (for example, ~/Views/Layout/DefaultDarkSidebar.cshtml) or a partial name (example: _Layout). When a partial name is provided, the Razor view engine searches for the layout file using its standard discovery process. The folder where the handler method (or controller) exists is searched first. This discovery process is identical to the process used to discover partial views. By default, every layout must call RenderBody. Wherever the call to RenderBody is placed, the contents of the view will be rendered. All available layout could be found in folder Views/Layout.

Partials

Global partials are located inside the Views/Shared Folder. You can use partials in your page views with a partial tag and in the attribute name specify the partial path you want to use.

<partial name="~/Views/Shared/PageTitle.cshtml"/>

public IActionResult Index()
{
     return View();
}

public IActionResult Index()
{
     return View("Views/Auth/SignUp.cshtml");
}
