What important difference exists between Monitor.TryEnter(object) And Monitor.TryEnter(object, ref bool)?

Question

It seems that these code snippets ought to behave identically:

1: Monitor.TryEnter(object)

if (Monitor.TryEnter(lockObject))
{
    try
    {
        Do         


        

Answer 1

1. Monitor.TryEnter could succeed and then an asynchroneous exception like ThreadAbortException or OutOfMemoryException (that can happen without visible allocations) is triggered. Then the lock would be taken but never released.
