  Hi Pankaj, using lock(_lock) we made the implementation thread-safe. If suppose we use directly if(instance == null) then there may come a scenario where two threads evalutes this statement as true and both the threads will end up creating an instance, which will violates the singleton pattern.

  Hello Arurva can you explain what is diff b/w both public static Singleton GetInstance { get { //to make implementation thread-safe lock (_lock) { if (instance == null) { instance = new Singleton(); } return instance; } } } and public static Singleton GetInstance { get { if (instance == null) { instance = new Singleton(); } return instance; } }
