Auto-completion of property names fails when capturing output from Out-GridView command

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

When a variable captures output, that is being piped through the Out-GridView command, the VSCode PowerShell extension is unable to auto-complete the property names from that variable.

The declared [OutputType()] seems to get "lost" from the Get-AzStorageAccount command, when it's piped through Out-GridView. Is there a way to preserve this?

Thanks for your submission!

It works fine for me, the vscode extension uses the same completion engine powershell does, so you have to run the first line before the runtime form of $test is known.

If you want completion without having to run the command in the extension terminal first, you have to type the variable, because PowerShell has no idea what type Out-Gridview will emit.

IF you want that to be inferred without running the command, that has to be "fixed" in PowerShell itself (if even possible).

Thanks @JustinGrote! I appreciate the screenshots and detailed description.

You're right that it works if the variable has been defined in the PowerShell session.

I did test this out in PowerShell, using Windows Terminal, but the obvious difference is that I had actually defined the variable there. Whereas, in the VSCode repro, I was not actually defining the variable. I didn't think about that.

Anyway, I can file this feedback in PowerShell instead of VSCode PowerShell extension! Much appreciated.
