Pipeline Tool-- operation could not be completed, parameter is incorrect

I’m getting this error in VS 2019 when I try to open the Pipeline from inside my solution-- I can open it from the file. Anyone else get this error? I’ve tried restarting VS, restarting my computer, deleting the .suo file. It also happens when I run VS as admin. I believe this started when I updated VS a day ago or so.



Hey Shoris,

I was having this issue as well, but seems fixed in the most recent version of VS2019 (16.5.3).

Unfortunately, it looks like this newest VS version introduced another bug:
VS does not open the content file in the pipeline tool unless you select ‘open with’ every time. VS totally ignores the ‘Default’ program.


I fixed this by re-adding the pipeline tool into default programs.


Thanks for the help!
