Linking MVC4 Models By ID - entity-framework

Question

Woke up yesterday wondering what all the fuss with MVC was about. So I found out and wow it's nice and stuff like that.
I'm used to using one related Linq to Sql DataContext DB in ASP.NET projects.
//Some ASP.NET Page Codebehind
DataContext dbEntire = new DataContext()
With MVC4 with the Entity framework you make the model and it creates a DB for you.
//Models/Article/Article.cs
public class ArticleDBContext: DbContext
{
public DbSet<Article> Articles { get; set; }
}
public class Article
{
public int ID {get;set;}
public string Title{ get; set; }
public int AuthorID { get; set; }
public string Body { get; set; }
public int CategoryID { get; set; }
public DateTime Submitted{ get; set; }
public DateTime LastModified { get; set; }
}
Author and Category are seperate Models.
But how do you set up all the database relations.. One to many, etc. etc. ?

Answer 1

public class ArticleDBContext: DbContext
{
public DbSet<Article> Articles { get; set; }
public DbSet<Category> Categories { get; set; }
}
public class Article
{
public int ID {get;set;}
public string Title{ get; set; }
public int AuthorID { get; set; }
public string Body { get; set; }
public int CategoryID { get; set; }
public virtual Category Category { get; set; }
public DateTime Submitted{ get; set; }
public DateTime LastModified { get; set; }
}
public class Category
{
public int ID {get;set;}
public string Name{ get; set; }
public virtual ICollection<Article> Articles { get; set; }
}
