Is there a way to do this without iterating through the List and adding the items to the ObservableCollection?

The true difference is rather straightforward:ObservableCollection implements INotifyCollectionChanged which provides notification when the collection is changed (you guessed ^^) It allows the binding engine to update the UI when the ObservableCollection is updated. However, BindingList implements IBindingList.
var myObservableCollection = new ObservableCollection<YourType>(myIEnumerable); This will make a shallow copy of the current IEnumerable and turn it in to a ObservableCollection.
No, there is no way to directly convert the list to an observable collection. You must add each item to the collection. However, below is a shortcut to allow the framework to enumerate the values and add them for you.
Dim list as new List(of string)
...some stuff to fill the list...
Dim observable as new ObservableCollection(of string)(list)
