Describe the bug

Unable to debug in in VSCode a console app that renders a table via AnsiConsole.Live(table).

Works as expected running directly from pwsh inside VSCode, and debugging from VS.

Stacktrace:

System.IO.IOException: 'The handle is invalid'

To Reproduce

Simplest code to reproduce it (debug from VSCode):

using Spectre.Console;

var table = new Table()
    .AddColumns("1", "2");

await AnsiConsole.Live(table)
    .StartAsync(async ctx =>
    {
    });

return;

Real project:

git clone https://github.com/eduherminio/AoCHelper
cd AoCHelper/src/AoCHelper.PoC
code .
<debug from VSCode>

Expected behavior
No exception is thrown

Screenshots

From someone consuming the library that has the spectre.console dependency via NuGet (eduherminio/AoCHelper#183)

From my PoC project (second repro above) that uses the library which spectre.console dependency via project reference

This error happens in more situations:

• When piping out the console output to another console.in. Exs:

mycode.exe > textoutput.txt

mycode.exe | more

• When running with SYSTEM account: (Download psexec from Microsoft site to run a command with the System account)

psExec -s mycode.exe

I believe this are the same issue than piping above. Psexec should be piping the result to show in the source console.

Hmm, since stdout is redirected, you shouldn't be able to do live output at all (by design). We will need to investigate this.

Just FYI I do check Environment.UserInteractive && !Console.IsOutputRedirected as a requirement to calling AnsiConsole.Clear(), after having issues with CI runners (#151), but never found an issue there with AnsiConsole.Live(table).
