* Add a folder named *Models*.
* Add a class to the *Models* folder named *Movie.cs*.
* Add the following code to the *Models/Movie.cs* file:
   [!code-csharp[Main](../../tutorials/first-mvc-app/start-mvc/sample/MvcMovie/Models/MovieNoEF.cs?name=snippet_1&highlight=7)]

In addition to the properties you'd expect to model a movie, the `ID` field is required by the database for the primary key. Build the app to verify you don't have any errors.

We've finally added a **M**odel to our **M**VC app.

## Prepare the project for scaffolding

- Add the following highlighted NuGet packages to the *MvcMovie.csproj* file:
             
   [!code-csharp[Main](start-mvc/sample/MvcMovie/MvcMovie.csproj?highlight=5,15-)]

- Select **Restore** to the **Info** message "There are unresolved dependencies".
- Create a *Models/MvcMovieContext.cs* file and add the following `MvcMovieContext` class:

   [!code-csharp[Main](start-mvc/sample/MvcMovie/Models/MvcMovieContext.cs)]
   
- Update the *Startup.cs* file and add two usings:

   [!code-csharp[Main](start-mvc/sample/MvcMovie/Startup.cs?name=snippet1&highlight=1,2)]

- Add the database context to the *Startup.cs* file:

   [!code-csharp[Main](start-mvc/sample/MvcMovie/Startup.cs?name=snippet2&highlight=5-7)]

- Add a database connection string to the *appsettings.json* file:

   [!code-csharp[Main](start-mvc/sample/MvcMovie/appsettings.json?highlight=7-)]

- Build and run the project to verify there are no errors.

### Scaffold the MovieController

Open a terminal window in the project folder and run the following commands:

```console
dotnet restore
dotnet aspnet-codegenerator controller -name MovieController  -m Movie -dc MvcMovieContext
```

The scaffolding engine creates the following:

* A movies controller (*Controllers/MoviesController.cs*)
* Create, Delete, Details, Edit and Index Razor view files (*Views/Movies*)

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

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

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

### Clean up the scaffolding

- Move the `MovieController.cs` file to the *Controlers* folder. By convention, controllers are in the this folder.

- Remove the `Layout` markup in each of the Razor view files in the *Views/Movie* folder. Remove the following  code:

 ```html
  @{
      Layout = null;
  }
 ```

   The `dotnet new mvc` generated code includes the *Views/Shared/_Layout.cshtml* Razor layout file which we'll use in each view. *Views/Shared/_Layout.cshtml* is automatically imported into each view with the *Views/_ViewStart.cshtml* Razor view file:

   [!code-csharp[Main](start-mvc/sample/MvcMovie/Views/_ViewStart.cshtml)]


[!INCLUDE[adding-model](../../includes/mvc-intro/adding-model3.md)]

You now have a database and pages to display, edit, update and delete data. In the next tutorial, we'll work with the database.
