1. Thread1 calls Foo and returns. Now isWorking=true, and PoolThread1 is processing DoSomething. No lock.
2. Thread2 calls Foo and returns. Still isWorking=true, and PoolThread2 is processing DoSomething. No lock.

I don't know why you want isWorking to be true in OnDoSomethingCompletedAsync

How does Thread2 see that isWorking = true?

void Foo()

     lock (syncObject)

         if (!isWorking)

             isWorking = true;
             new Action(DoSomething).BeginInvoke(OnDoSomethingCompletedAsync, null);
