The external locking mechanism is as he shows in his example in the question: lock (m_MySharedDictionary.SyncRoot) { m_MySharedDictionary.Add(); } -- it would be perfectly safe to do the following: lock (m_MySharedDictionary.SyncRoot) { if (!m_MySharedDictionary.Contains()) { m_MySharedDictionary.Add(); } } In other words, the external locking mechanism is the lock statement that operates on the public property SyncRoot.
