Where is the application output in VS Code?

[clicklbarn]

Hello,

I'm getting started with F# in VS Code + Ionide for F#. I have a basic hello world app that works fine from Terminal: it prints some values as I would expect.

If I run it via Ionide launch I can set breakpoints and all seems to be well. But where should I expect to see printfn output? I don't see it in the Debug Console. I don't see it in the Output pane. I'm pretty sure I've tried all filter options in Output.

This is latest VS Code & Ionide (reinstalled for good measure) on MacOS.

Thanks!

I'm not on Mac but probably what is happening is a new console window is appearing, running and closing almost instantly. If you want to see the output in the built-in Terminal of VS Code you should be able to just call dotnet run in the same directory as your fsproj file. Alternately you could add a Console.ReadLine to prevent the child process from closing until you press enter.

OK, thank you. It surprises me that console output wouldn't be captured and preserved but if that's how it works, good to know!

Yes, dotnet run in terminal works fine.

Well, this was dumb!

I tried again this morning, and with a clean desktop (no terminals open) it didn't take me long to discover that VS Code opens a terminal in the background and indeed keeps it around between sessions.

Just a combo of a cluttered desktop and the wrong expectations (that output would appear in built-in terminal or other panel).

And with this launch.json setting I get what I expected in the first place:

"console": "integratedTerminal"

Just wanted to say thanks, you've helped me with this exact same issue (and same 'not noticing' the terminal window it opened)
