One way to solve this is to add a new FK property to your Product entity:

public class Product
{
    public int ProductID { get; set; }        
    public string ProductName { get; set; }
    public Decimal? UnitPrice { get; set; }
    public bool Discontinued { get; set; }
    [ForeignKey("Category")]
    public int CategoryId { get; set; }

    public virtual Category Category { get; set; }
}
