Child process exits immediately after running any command in TermControl ported to WinUI 3

[lgztx96]

I ported TermControl to WinUI 3 and it works, but no matter what command I run, the child process exits very quickly. I’m not sure what steps I might be missing, or how to troubleshoot this issue. Any help would be greatly appreciated.
cmd

custom console app


I debugged it and found that ReadFile returned 109, which means the pipe has been disconnected. I’m sure I didn’t perform any special operation.

Building openconsole.exe(HOST.EXE project) solved my problem.

This is amazing work! So sorry for the delay in responding--we're doing release engineering stuff at the moment, so we're a bit distracted. Glad you got it sorted!
