Original Pull Request: https://github.com/microsoft/terminal/pull/7741

State: closed
Merged: Yes

This pull request is in support of WTU.

I initially added support for a new flag, PSEUDOCONSOLE_UNDOCKED_PREFER_INBOX_CONHOST, which I liked because it was more explicit. You can see that approach in commit cae3289cf.

Consider this an open discussion. Should we automatically fall back? Or should we allow a developer to opt for fallback?

Automatic fallback

Pros

  • It's easier on the consumer
  • We can eventually expand it to support $ARCH/openconsole.exe

Cons

  • Packaging the project wrong will result in a working-but-somewhat-broken experience (old conhost)
  • Implicit behavior may be bad

Manual selection

Pros

  • Consumer gets explicit control

Cons

  • Consumer must explicitly opt in. In the case of WTU, that means pushing a configuration down into TerminalConnection all the way from TerminalApp to say "use the inbox one, dummy"
