public void SaveChanges()

{

foreach (Entity entity in this.Items)

{

if (DataRowState.Detached == entity.EntityState)

{

context.AddObject(entity);

}

context.SaveChanges();

}

Note i've changed Entity.Detached by DataRowState.Detached since in my bits, that is the type of EntityState (for an entity)

So far it runs this way, testing this :D

I'm missing something here? I'm very new to ADO.Net vNext

ObjectContext.AddObject(entity) is no longer supported (?). The is another overload

ObjectContext.AddObject("entitySetName", entity)

How do I find out the correct EntitySet name having just generic Entity type (T) available?

I have been able to successfully implement a custom binding list entity such as your example. I cannot however, get this to work in a situation where I have nested binding source objects on a winform in order to achieve master-detail binding. How would one inject in to ObjectQuery<TEntity> or EntityCollection<T> to override the IListSource interface so that the GetList() member of IListSource could return my custom EntityBindingList<TEntity>?
