• If this is a security issue, I have read the security issue reporting guidance.

Summary

Good evening

The vscode-powershell implementation of the "inplace PowerShell 7 update" is unfortunately terribly awkwardly implemented and it's random if the PowerShell 7 update works at all.
In the most embarrassing case, the PowerShell 7 update works like this:

1. the VS Code Extension reports the PowerShell 7 update
2. the PowerShell 7 update detects that VS Code has started pwsh.exe and aks if it should stop the exe
3. if the user chooses that the setup should terminate pwsh.exe, it happens that VS Code is terminated as well.
4. because VS Code is terminated, the PowerShell 7 setup is also killed

It would be much more useful if the VS Code vscode-powershell Extension would just offer two links if it detects the update:
Link 1: Link to the Setup exe. If the user clicks to the link, the web browser is opened, so that the setup will work for sure (it must be starte independent of VS Code)
Link 2: Link to the release notes.

Thanks a lot, kind regards,
Thomas

Steps to Reproduce

1. Wait, until the vscode-powershell extension reports a PowerShell 7 update
2. Start the Update from the vscode-powershell extension pupup dialog
3. The PowerShell 7 update usually gets a nightmare which ends in the user is using google for PowerShell 7 update, downloads the setup exe himself and install it without VS Code and the vscode-powershell extension

if the user chooses that the setup should terminate pwsh.exe, it happens that VS Code is terminated as well.

This shouldn't be happening at all and is a bug.

Link 1: Link to the Setup exe. If the user clicks to the link, the web browser is opened, so that the setup will work for sure (it must be starte independent of VS Code)

This is actually what happens in every case except when an MSI is available (try it out on macOS, Linux, or an Arm64 Windows).

I'll take a look a the bug where Code is terminating, and TBH I wanted to remove the auto-install logic around the MSI at the time we updated the code anyway, since I didn't think it could be that reliable. Turns out it's not!

Thanks for the report.
