Extensions specified in devcontainer.json file do not install in the correct extension host

Body

As outlined over at:

microsoft/vscode#154563

VS Code web extensions specified in a devcontainer.json file on codespaces do not install in the correct extension host. From that issue:

• VS Code Version: 1.69.0 (codespaces)
• OS Version: MacOS 12.4 (chrome)

Steps to Reproduce:

1. Use/identify an extension which can run in different extension hosts depending on host availability following the pattern agreed in Allow running remote extensions in the web worker extension host microsoft/vscode#141322 (e.g. arm.device-manager)
2. Create a GitHub repository containing a devcontainer.json file with this extension (e.g. this one)
3. Create a codespace on that repository and observe all extensions are installed in the remote host as codespace extensions

Expected behaviour - the multi-host extension should install as a web extension into browser extensions.

When installing this extension manually, it behaves correctly:

Hey @thegecko sorry you're not having the experience you expect.

I'll file a ticket to discuss this further. In the meantime, if you're able to, it might be worth trying to override the installation location in the settings.json file--that could be a potential work around (although I haven't tried it myself).

Hi @thomas-sickert,
I was running into the same problem as @thegecko and unfortunately the suggested workaround does not work for me.
My settings file looks like this:

{ "remote.extensionKind": { "arm.device-manager": [ "ui" ] } }

Do you see any other workaround or do I have to wait until the issue is fixed?

I can also confirm this work around doesn't work.

The closest I've got is to use an extensions.json file to recommend extensions the user installs. This still means the extensions don't appear automatically, but do end up in the right host if the user installs them.

@thomas-sickert is there any progress on fixing this or a way I can escalate it?

This is still an issue and VS Code extensions marked as ui are getting installed in the codespaces host.

Any update @thomas-sickert ?
