In this section you'll add some classes for managing movies in a database. These classes will be the "model" part of the ASP.NET MVC application.
You'll use a .NET Framework data-access technology known as the [Entity Framework](https://msdn.microsoft.com/en-us/library/bb399572(VS.110).aspx) to define and work with these model classes. The Entity Framework (often referred to as EF) supports a development paradigm called *Code First*. Code First allows you to create model objects by writing simple classes. (These are also known as POCO classes, from "plain-old CLR objects.") You can then have the database created on the fly from your classes, which enables a very clean and rapid development workflow.
## Adding Model Classes
In **Solution Explorer**, right click the *Models* folder, select **Add**, and then select **Class**.
Enter the *class* name "Movie".
Add the following five properties to the `Movie` class:
We'll use the `Movie` class to represent movies in a database. Each instance of a `Movie` object will correspond to a row within a database table, and each property of the `Movie` class will map to a column in the table.
In the same file, add the following `MovieDBContext` class:
The `MovieDBContext` class represents the Entity Framework movie database context, which handles fetching, storing, and updating `Movie` class instances in a database. The `MovieDBContext` derives from the `DbContext` base class provided by the Entity Framework.
In order to be able to reference `DbContext` and `DbSet`, you need to add the following `using` statement at the top of the file:
## Creating a Connection String and Working with SQL Server LocalDB
The `MovieDBContext` class you created handles the task of connecting to the database and mapping `Movie` objects to database records. One question you might ask, though, is how to specify which database it will connect to. You'll do that by adding connection information in the *Web.config* file of the application.
Open the application root *Web.config* file. (Not the *Web.config* file in the *Views* folder.) Open the *Web.config* file outlined in red.
Add the following connection string to the `<connectionStrings>` element in the *Web.config* file.
