Yes, because you need to provide an implementation for all methods of
the interfaces that the class references.

IList.IsReadOnly is an implicit interface method implementation. It
means that, although it is private, you can access to it using the
interface. So, for example:

myCollection.IsReadOnly()	// This gives a compilation error
((IList)myCollection).IsReadOnly()	// This works
