@mcj-codificer, Thank you. I updated the script as you suggested.

Thank you for this! Do you know of any way I can merge this into a single script or if there is a way to push to multiple devices in an Azure environment?

There are a list of extensions that I'd like to be able to push to my dev team using a remote management tool or by uploading a script in Azure to push to specific devices.

Do I have to use Edge or Internet Explorer to sign in, or will any browser (Chrome/Firefox etc) work?

This is in regards to the comment thread about avoiding the rate limits. Thank you.

I note that on line 13 the script sets the $VSInstallDir variable to C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\ServiceHub\Services\Microsoft.VisualStudio.Setup.Service which is correct.

However, on line 16, if this variable refers to the pathname of a folder that does not exist on the computer, it says Visual Studio InstallDir registry key missing. I am wondering, is the error message inconsistent?

In VS 2022, the VSIXInstaller is by default located at:

C:\Program Files\Microsoft Visual Studio\2022\Professional\Common7\IDE\

If using the Developer PowerShell prompt, environment variable DevEnvDir can be used for that path.

This doesn't quite work (running an adapted version of this code):

==> default: Running provisioner: rust_analyzer_vs (shell)...
    default: Running: inline PowerShell script
    default: Where-Object : The property 'class' cannot be found on this object. Verify that the property exists.
    default: At C:\tmp\vagrant-shell.ps1:10 char:3
    default: +   Where-Object { $_.class -eq "install-button-container" } | `
    default: +   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    default:     + CategoryInfo          : NotSpecified: (:) [Where-Object], PropertyNotFoundException
    default:     + FullyQualifiedErrorId : PropertyNotFoundStrict,Microsoft.PowerShell.Commands.WhereObjectCommand
    default:

The issue is that not all links on the page have a class. Changing the Where-Object part to:

Where-Object { $_.PSObject.Properties.Match('class').Count -and `
        $_.class -eq "install-button-container" }

seems to work.

Thanks for the fix. I haven't used these scripts for a couple years, since we only use two or three extensions now, and recently we have no Internet access on our developer machines.
