Entity Framework CTP4 Code First: Mapping protected properties

Question

I would like to use a lazy-loading collection on a model, but I want Add/Remove functionality to be done through separate methods. So something like this:

class Model
{
  protected virtual ICollection<Something> _somethings { get; set; }

  public IEnumerable<Something> Somethings 
  { 
    get { return _somethings; } 
  }

  public void AddSomething(Something thingToAdd)
  {
    /*  logic */
    _somethings.Add(thingToAdd);
  }
}

I can't figure out how to configure the mapping for this. I looked into using a configuration class: EntityConfiguration. But since the property is protected I can't figure out how to set a configuration on it. Is there any way to accomplish what I'm trying to do here?

Answer 1

I suppose if you declare the configuration class (inheriting EntityConfiguration) inside your Model class, it could work. It's not a nice solution, since subclassing is generally discouraged, but it's the only thing I can think of.
