Issue Description

When typing in the IC directly, Enter key does not work anymore

I don't have this issue with 7.0.3

I captured the logs while pressing enter a bunch and then Ctrl+C

Expected Behaviour

Should work.

Actual Behaviour

Does not work

Attached Logs

Follow the instructions in the troubleshooting docs
about capturing and sending logs.

I'm not able to reproduce this myself, but we'll try on macOS as well

[bgelens]

Thanks @rjmholt! FYI, no change when not loading my profile. Also tried the stable PowerShell extension, same issue

[TylerLeonhardt]

I can repro this on macOS. It's likely a regression in PowerShell.

[TylerLeonhardt]

you can go back to preview6 or powershell.integratedConsole.useLegacyReadLine still works until we get to the bottom of this.

[bgelens]

I'm fine working with 7.0.3 daily. Noticed it as I'm preparing a demo for tomorrow "whats new in 7.1" :)

I'll leave my setup as is in case you require some additional info / actions from my side

[TylerLeonhardt]

Thanks for bringing this to our attention!

[bgelens]

Small update: If I hit enter right after the IC is available (started), it will work a couple of times (like in a 1 sec window)

[TylerLeonhardt]

I've been swamped with Ignite stuff but I'll focus on this right after that's done.

[TylerLeonhardt]

This appears to be an underlying issue with .NET: https://github.com/dotnet/runtime/issues/42418

[TylerLeonhardt]

They ack'd. Closing this as external. .NET 5 RC.2 will likely have this sorted. This could be the next preview of PowerShell or the one after. cc @SteveL-MSFT @daxian-dbw @rjmholt

@TylerLeonhardt @SteveL-MSFT @daxian-dbw @rjmholt Can confirm the problem is resolved with RC2!
