In Day 3 we are going to cover Authentication in more details. One of the benefits of MVC is "Unit" test. Because you do not have behind code and controllers have become simple classes you can unit test controllers very easily. But for now we will keep this option unselected as our main intention is to display hello world. Let's spend some time in understanding the solution created. The first thing you will notice is that there are lot of folders created, see the below figure.

The most important from these folders is the "View" , "Model" and "Controllers" folder. MVC architecture is divided in to three sections model, view and controller. So the first hit comes to the controller , he creates the object of model and view and sends the final response to the end user. Model In this folder you will add model classes. Models are simple. NET classes which provides data and probably also contain validations. So in this folder you will add Customer class, Supplier class etc.

Controller In this folder you will add controller and controllers can have actions. This guy is responsible for taking the request from the end user, invoking the appropriate actions, creating object of the model and then tieing up the view and model together to send the results as response.

Content This folder has CSS Cascading style sheet which gives a uniform look and feel for your project. So this folder is created when you store data in files.

Fonts In case you fonts which you are using in your web application you can put them here. Step 3: - Add Controller The next step is to add the controller. Go to the controllers folder , right on click and click the controller menu as shown in the below figure.

The next screen which comes up is to select "Scaffold" templates. CRUD stands for create, read, update and delete. But at this moment we are learning MVC so selecting Scaffolding or readymade code is not a good option.
