Debug.Assert(!rwLock.IsWriteLockHeld, 
    String.Format("Thread {0} is still holding the write lock after MyFunction has finished.", 
                  Thread.CurrentThread.ManagedThreadId));
Debug.Assert(Not rwLock.IsWriteLockHeld, _
    String.Format("Thread {0} is still holding the write lock after MyFunction has finished.", _
                  Thread.CurrentThread.ManagedThreadId))
