What is ERROR 404?

The HTTP error 404, or more commonly called "404 error", means that the page you are trying to open could not be found on the server. This is a client-side incident which means either the page has been deleted or moved, and the URL has not been modified accordingly, or that you have misspelled the URL.

Lets Say You have a Simple Asp.Net Core Webapp. When you Open it you can find a folder called Pages. In Pages Folder you can find files with .cshtml extensions. Most Commonly in a Simple Webapp you can find Index.cshtml and Privacy.cshtml. if you run the app and you navigate to the URL https://localhost:5001/index1 you'll get an ERROR 404. this is Because in our Project there is no pages named Index1.cshtml.
