Why doesn't Mutex get released when disposed?

Question

I have the following code:

using (Mutex mut = new Mutex(false, MUTEX_NAME))
{
    if (mut.WaitOne(new TimeSpan(0, 0, 30)))
    {
       // Some code that dea         


        

Answer 1

Reading the documentation for ReleaseMutex, it seems the design decision was that a Mutex should be released consciously. if ReleaseMutex isn't called, it signifies an abnormal exit of the protected section. putting the release in a finally or dispose, circumvents this mechanism. you are still free to ignore the AbandonedMutexException, of course.
