Complete beginner at C# MVC 4 - just trying to learn its basic structure. Currently if I run this project: 

[![enter image description here](https://i.stack.imgur.com/hGR9x.png)](https://i.stack.imgur.com/hGR9x.png)

The page and URL look like this:

[![enter image description here](https://i.stack.imgur.com/fSAkY.png)](https://i.stack.imgur.com/fSAkY.png) 

Apparently the code that sets this path as the default URL for the home page is in /App\_Start/RouteConfig.cs, lines 22 and 23:

```
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }

```

Now say that I want to enter a path that doesn't exist yet, like this:

`localhost:64653/home/foo`

What do I need to do in order to create this path? Would I need to create a `foo.cshtml` file within views? What else do I need to add to the `Controllers` folder in order to allow this view to exist? Thank you!
