I have a POCO (Plain Old CLR Object)

```
public Foo
{
   public virtual int Id { get; set; }
   public virtual Dictionary<string, string> Stuff { get; set; }
   public virtual string More { get; set; }
}

```

Using the [model first](http://msdn.microsoft.com/en-us/data/ff628199.aspx) approach (i.e. I don't have a data model yet), how would I handle persisting Stuff (Dictionary)?
