Question

Within the realm of Entity Framework, if I have 2 seperate classes leveraging a data model, do I need to ensure that there is only 1 reference to the entities object (singleton or similar)? In other words, in the scenario below, is there any danger?

public class Foo
{
    public void DoSomething()
    {
        using (MyEntities entities = new MyEntities())
        {
            //use _entities in some fashion here
        }
    }
}

public class Bar
{
    public void DoSomething()
    {
        using (MyEntities entities = new MyEntities())
        {
            //use _entities in some fashion here
        }
    }
}

Thanks.
