I need to clear some old entries saved for Connection target dropdown list in Attach to Process dialog. Some remote servers have been decommissioned. But their names are still listed on the top of Connection target list. When I start the Debug menu command "Attach to process", it takes awhile trying to connect to an old server that is not connectable. Google search doesn't return the answer of where the list is saved.
Hopefully someone can provide the answer.
After quite some digging I've found the answer you might be after (if you still need it), the web page you'll need is at Microsoft Learn.
If you want to dive straight in have a look in the Tools Menu under Options and then find Cross Platform and Connection Manager:
I'm using Visual Studio 2022 17.4.3 (current version as of Jan 2023) just in case other versions have a different layout.
