Issue Description

Today, I've received a few 'Extension host terminated' errors when I was editing the code while being disconnected from the network (LAN not connected and WiFi adapter disabled). When I hit this it reminded me about issue #353 (if wonder if these are related), although in my case I wasn't trying to run a debugger but just was editing some PS code.

Hey @Glober777, do you still see this issue in more recent builds of VS Code and the PS extension?

[Glober777]

Hey @daviwil, I haven't faced with this issue since I submitted a bug for it, however I haven't been using VSCode offline either.

[daviwil]

No problem! I'll try to reproduce this sometime and see if I hit the same issue before I close this bug.

There is still an issue there @daviwil @Glober777. I don't receive a error message. However the extension reports "Starting PowerShell..." and never completes.

Thanks @BernieWhite! Your logs look clean, but perhaps we're missing some context without Verbose logs turned on. Can you turn on verbose logs and try it again?

Judging from what I see here, the language server fully starts up but maybe there's some problem preventing the integrated console from showing the initial prompt.

Hi David

Same issue on my system. If I start Visual Studio Code with the PowerShell extension when I'm completely offline, like in the train, the PowerShell host is starting forever:

This are the log files with verbose turned on:
EditorServices.txt
vscode-powershell.txt

I can see that the PowerShell Editor Service is listening on 127.0.0.1:23623

And the good old telnet to the local port 23623 works too. So no localhost network issue.

I'm having the same issue, is there anything I can do to help troubleshooting this?

[TylerLeonhardt]

This should be fixed in #1327 since we are no longer relying on TCP sockets in the extension.
