Question: I am new to Visual Studio and C# in general. I'm following a tutorial trying to learn the language ([tutorial here](http://weblogs.asp.net/scottgu/archive/2011/05/05/ef-code-first-and-data-scaffolding-with-the-asp-net-mvc-3-tools-update.aspx)). 

One of the steps is to **add a “using” statement to the System.Data.Entity namespace at the top of the class file (in order to reference the DbContext and DbSet classes)**. This can be found under step 3.

I'm hoping someone can help me out with this section. I've searched on here and Google for an answer, but since I'm new to the language I can't seem to find the correct answer. Any help would be greatly appreciated!

Answer: 
At the top of your file there should be couple lines, each starting with `using` and namespace after that keyword.

Add another one there, to the namespace mentioned in your tutorial:

```
using System.Data.Entity;

```

You can find more information about `using` on MSDN: [`using` Directive (C# Reference)](http://msdn.microsoft.com/en-us/library/sf0df423.aspx)
You can press Ctrl + . (dot) in Visual Studio and using statement will be added automatically.
