c# - Prevent program from closing when console window closes -

so happening console program opens runs external c# program/code text file. runs fine when close original form window program/code executed closes. there way prevent text file code running closing?

this code calling run program

static void memexe(byte[] buffer)         {             assembly asm = assembly.load(buffer);              if (asm.entrypoint == null)                 throw new applicationexception("no entry point found!");              methodinfo epoint = asm.entrypoint;             epoint.invoke(null, null);         } 

where buffer code/program in bytes

and main

static void main(string[] args)         {             var data = file.readalltext(@"program.txt");             memexe(data);         } 

a workaround change project's output type in project's properties -> application -> output type console application windows application (see screenshot)

this way no console window created, the process neither appear 2 running processes nor can terminated closing console window.

this approach take. method executed in non-background-thread prevents process terminating once main-thread has terminated. however, still cannot close console window. that's why suggest switching windows application
