Routing In ASP.NET Core

This article describes routing in ASP.NET Core.

Routing The ASP.NET MVC Application

In an ASP.NET MVC application, we have a routeconfig.cs file, where we write routing rules. It is not required that the URL is mapped to the physical files.

Routing In ASP.NET Core

In the case of the ASP.NET Core routing, we have the following rules: -

Rule	URL	Description
Routes are mapped to physical view files.	http://localhost/index	The URL maps to the physical file index.cshtml.
Index.cshtml is the default document.	http://localhost	The URL maps to the physical file index.cshtml.
The folder name is added to the URL.	http://localhost/Admin/privacy	The URL is assigned to privacy.cshtml within the Admin folder.
