This member is an explicit interface member implementation. It can be used only when the ReadOnlyDictionary(Of TKey, TValue).KeyCollection instance is cast to an ICollection(Of T) interface. The ICollection(Of T) interface specifies that the Remove method should throw a NotSupportedException exception if the collection that implements the interface is read-only.
