Possible duplicate: Run single instance of an application using Mutex
I am using VS 2008 in C# on a console application. Not sure if there is any class available (process?) to limit only single console application running at a time.
- Did you mean to run just one instance of the program?Alan Haggai Alavi– Alan Haggai Alavi2009-06-03 04:42:20 +00:00Commented Jun 3, 2009 at 4:42

There is no such class, but you can use System.Threading.Mutex to build one.
Mutex is a synchronization primitive that can also be used for interprocess synchronization.
See example: How ensure that only one instance of an application will run?

I quickly slapped this together, but it does show the second console briefly and then hides it. Not sure if there's a way to block the second console from even showing up...
class Program { private static Mutex mutex; static void Main(string[] args) { mutex = new Mutex(true, "MyMutex"); if (!mutex.WaitOne(0, false)) { return; } Console.WriteLine("Application started"); Console.ReadKey(true); } } You'll need to add a reference to System.Threading.
