When you run an application its instance is created in process
so if you need to see that its instance already running

C#

string procName = Process.GetCurrentProcess().ProcessName;
  if (Process.GetProcessesByName(procName).Length == 1)
  {
      ...code here...
  }

Or you can directly set it from Project properties Preventing multiple instances of .Net Applicationl[^]

You can do it in any of the way
