It seems after almost a year, this problem still exist.
To be specific, after I started a debug process and open Rhino from VS and do some work, when the process crashes or I kill it from VS, the Rhino process will be killed, but the compute.compute process will not.
As a result, I need to open the “Task Manager” and manually kill it.
This issue won’t happen 100% of the time, but from my experience, 60% - 80% of the time I need to do it.
