Doom9's Forum - View Single Post - implementation to force player being single instance

Quite easy to do with the Win32 API:

Code:

::CreateMutex(NULL, TRUE, "__my__app__single__instance__lock__"); //make sure that string is unique

if (::GetLastError() == ERROR_ALREADY_EXISTS)
{
 printf("One instance of this program is already running");
 return;
}

Should be easy to transpose to C#.

BTW, first hit on Google:https://stackoverflow.com/questions/...app-in-c-sharp
