/Models

Models hold and manipulate data

/Content

This folder holds our images, CSS, and any other static content

/Scripts

This folder holds our JavaScript files

These folders are included even in an Empty ASP.NET MVC application because the ASP.NET MVC framework by

default uses a “convention over configuration” approach and makes some default assumptions based on folder

naming conventions. For instance, controllers look for views in the Views folder by default without you having

to explicitly specify this in your code. Sticking with the default conventions reduces the amount of code you

need to write, and can also make it easier for other developers to understand your project. We’ll explain these

conventions more as we build our application.

2. Controllers

With traditional web frameworks, incoming URLs are typically mapped to files on disk. For example: a request

for a URL like "/Products.aspx" or "/Products.php" might be processed by a "Products.aspx" or "Products.php"

file.

Web-based MVC frameworks map URLs to server code in a slightly different way. Instead of mapping incoming

URLs to files, they instead map URLs to methods on classes. These classes are called "Controllers" and they are

responsible for processing incoming HTTP requests, handling user input, retrieving and saving data, and

determining the response to send back to the client (display HTML, download a file, redirect to a different URL,

etc.).

Adding a HomeController

We’ll begin our MVC Music Store application by adding a Controller class that will handle URLs to the Home

page of our site. We’ll follow the default naming conventions of ASP.NET MVC and call it HomeController.

Right-click the “Controllers” folder within the Solution Explorer and select “Add”, and then the “Controller…”
