I have a loader.exe with Main() that loads the 'UI' in WPF, the thing is that I want only one instance of the loader.exe, how can I achieve it?

Is there a way a user clicks loader.exe it should check if an existing loader.exe is running and does nothing.

currently I have

loader.exe

with 

main() 
....
..
Load UI
...

the loader has no idea what its loading etc so I can't do many things with the loader project...

Any help n code is highly appreciated

Thanks in advance.

We use the following C# code to detect if an application is already running:

using System.Threading;

string appSpecificGuid = "{007400FE-003D-00A5-AFFE-DA62E35CC1F5}";    
bool exclusive;
Mutex m = new Mutex(true, appSpecificGuid, out exclusive);
if (exclusive) {
    // run
} else {
    // already running
}

  • This sorta worked in my case with my loaded code that did all the initialization untethered. Thanks – abmv Nov 23 '08 at 11:30
