Hi I made following program
using System;
using System.Threading;
namespace mutex
{
class Program
{
static void Main(string[] args)
{
Mutex mutex =null , mutex1 =null;
string mutexName = "test";
try
{
mutex = new Mutex(false /*initiallyOwned*/, mutexName);
mutex.WaitOne(0, false);
mutex1 = new Mutex(false /*initiallyOwned*/, mutexName);
mutex1.WaitOne(0, false);
}
finally
{
Console.WriteLine("released mutex");
Thread.Sleep(30000);
if (null != mutex1) mutex1.ReleaseMutex();
if (null != mutex) mutex.ReleaseMutex();
}
}
}
}
The exe should block after 2nd waitone call as would have locked the mutex till release mutex is called. But it does not stop at 2nd waitone why?
