Note that the IsReadOnly flag comes from ICollection, and indicates whether items emanet be added or removed from the collection; but just to really confuse things, it does not indicate whether they can be replaced, which in the case of Arrays (which return IsReadOnlys == true) can be.

Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that uses your class.

If you use the concrete type all callers need to be updated. If exposed as IList the caller doesn't have to be changed.
If you had used IList in the rest of the app you could extend List with your own custom class and still be able to pass that around without refactoring.
