How to change database with Entity Code First in ASP.NET MVC3

While implementing a project with Entity Code First, I found out an interesting thing to share. In the project I made a personal blog. Here I create a class that contains the attributes, in this case a Table

I create a class Article with properties, including:

public class Article
{
    //[Key]
    public int ArticleId { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }
    [Required]
    [Column(TypeName = "ntext")]
    [MaxLength]
    public string Content { get; set; }

    private DateTime _datetime = DateTime.Now;
    public DateTime DateTime {
        get { return _datetime; } set { _datetime=value;} 
    }
    public int Hot { get; set; }
    public string AccountId { get; set; }
    public int CategoryId { get; set; }
    public int Active { get; set; }
}

Next, I create a DbContext for generating class Article into Table Article:

public DbSet<Article> Article { get; set; }

Then, I change in Global for section Application_Start:

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RegisterGlobalFilters(GlobalFilters.Filters);

    RegisterRoutes(RouteTable.Routes);
    Database.SetInitializer<BlogContext>(null);            
}

Then press F5 for run project.

Happy coding!
