从子控制台进程重定向到父控制台进程的控制台输出失败

Question

I have a console program as a parent process which runs several sub-processes which are also console programs. For the child processes, output is redirected to a pair of StringBuilder objects (one for STDOUT and one for STDERR.). Upon completion of a child process, its output is appended to the parent's output (also accrued in a pair of StringBuilder's.)

I recently added a new child process and it does not work. It doesn't fail either. I can't seem to debug it since no output statements in the child process work. I have spent a day trying to figure this out. Things are complicated a bit since the execution platform is on another server under control of the JAMS Scheduler.

Answer 1

The new child process used the most recent dotnet framework loaded on my development system - 4.6.1. The master process and the older child processes used 4.5.1. I verified using the dword "Release" at registry key "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\Full" that 4.6.1 was indeed installed on the server.

I changed the version of the new project to match the parent project (and other child projects), rebuilt and redeployed it and everything started working.

Hopefully, this will save one person a day of their life.
