[!INCLUDE[adding-model](../../includes/mvc-intro/adding-model1.md)]

In Solution Explorer, right click the **MvcMovie** project > **Add** > **New Folder**. Name the folder *Models*.

Right click the *Models* folder > **Add** > **Class**. Name the class **Movie** and add the following properties:

[!code-csharp[Main](../../tutorials/first-mvc-app/start-mvc/sample/MvcMovie/Models/MovieNoEF.cs?name=snippet_1)]

The `ID` field is required by the database for the primary key. 

Build the project to verify you don't have any errors. You now have a **M**odel in your **M**VC app.

## Scaffolding a controller

In **Solution Explorer**, right-click the *Controllers* folder **> Add > Controller**.

![view of above step](adding-model/_static/add_controller.png)

In the **Add MVC Dependencies** dialog, select **Minimal Dependencies**, and select **Add**.

![view of above step](adding-model/_static/add_depend.png)

Visual Studio adds the dependencies needed to scaffold a controller, but the controller itself is not created. The next invoke of **> Add > Controller** creates the controller. 

In **Solution Explorer**, right-click the *Controllers* folder **> Add > Controller**.

![view of above step](adding-model/_static/add_controller.png)

In the **Add Scaffold** dialog, tap **MVC Controller with views, using Entity Framework > Add**.

![Add Scaffold dialog](adding-model/_static/add_scaffold2.png)

Complete the **Add Controller** dialog:

* **Model class:** *Movie (MvcMovie.Models)*
* **Data context class:** Select the **+** icon and add the default **MvcMovie.Models.MvcMovieContext**

![Add Data context](adding-model/_static/dc.png)

* **Views:** Keep the default of each option checked
* **Controller name:** Keep the default *MoviesController*
* Tap **Add**

![Add Controller dialog](adding-model/_static/add_controller2.png)

Visual Studio creates:

* An Entity Framework Core [database context class](xref:data/ef-mvc/intro#create-the-database-context) (*Data/MvcMovieContext.cs*)
* A movies controller (*Controllers/MoviesController.cs*)
* Razor view files for Create, Delete, Details, Edit and Index pages (*Views/Movies/\*.cshtml*)

The automatic creation of the database context and [CRUD](https://en.wikipedia.org/wiki/Create,_read,_update_and_delete) (create, read, update, and delete) action methods and views is known as *scaffolding*. You'll soon have a fully functional web application that lets you manage a movie database.

If you run the app and click on the **Mvc Movie** link, you'll get an error similar to the following:

```
An unhandled exception occurred while processing the request.
SqlException: Cannot open database "MvcMovieContext-<GUID removed>" 
requested by the login. The login failed.
Login failed for user Rick
```

You need to create the database, and you'll use the EF Core [Migrations](xref:data/ef-mvc/migrations) feature to do that. Migrations lets you create a database that matches your data model and update the database schema when your data model changes.

## Add EF tooling for Migrations

- In Solution Explorer, right click the **MvcMovie** project > **Edit MvcMovie.csproj**.

   ![SE meu showing Edit MvcMovie.csproj](adding-model/_static/edit_csproj.png)

- Add the `"Microsoft.EntityFrameworkCore.Tools.DotNet"` NuGet package:

[!code-xml[Main](start-mvc/sample/MvcMovie/MvcMovie.csproj?range=22-25&highlight=3)] 

Note: The version numbers shown above were correct at the time of writing.

Save your changes.
