I frequently expose typed collections and lists. Often when exposing collections and lists I am not happy with the Add and Remove methods being public. In older versions of .Net I have implemented IEnumerable but this is a lot of work.

    you can have a private IList<T> you’ll be adding objects to, and the ReadOnlyCollection<T> will be a wrapper around this list. Since it’s a wrapper, all changes to an underlying list will be reflected in this read-only collection.
