Could this cause multiple identical GUIDs?

Question

As GUID generation is time-dependent, if System.Guid.NewGuid() is called multiple times at the exact same instant on different threads, could it return identical GUIDs?

Answer 1

Unless your threads are running on different cores on your machine, only one thread will be actually running at a given time. Hence, I do not think it is very likely that calls to NewGuid() will take place at the exact same time.
