Incorrect errors shown when launching in remote container (Codespaces)

Type: Bug

When a remote Codespaces container is built and loaded in VSCode for the first time, VSCode seems to be parsing task.json or recommending extensions in parallel with installing extensions in devcontainer.json. This leads to:

1. False-positive errors printed out around parsing task.json (due to an extension installed type not being recognized), and
2. Extension being recommended to be installed even though it is specified in devcontainer.json.

To reproduce:

VSCode browser:

1. Go to https://github.com/Azure-Samples/todo-python-mongo
2. Click on ‘Code’ -> Create Codespaces environment
3. Wait for Codespaces environment to be fully available

VSCode desktop:

1. Have Codespaces extension installed.
2. Use Codespaces: New Container and select Azure-Samples/todo-python-mongo
3. Wait for Codespaces environment to be fully available

Expected: VSCode should load without any errors.

Actual:

1. In the terminal Output, errors printed our regarding "There is no registered task type ‘dotenv’. Even thought this dotenv task type is specified by an installed extension (azure-dev).
2. In the bottom right corner, a installer recommendations for “Azure Developer CLI” extension pops up.

That’s very peculiar, since the Azure Dev extension (with the same identifier) is already installed:

[alexr00]

@meganrogge you’re probably correct on the cause. I don’t recall seeing this before.

[meganrogge]

I think this has probably been occurring for awhile and is now noticeable with this change that made automatic tasks run by default in trusted workspaces

https://github.com/microsoft/vscode/pull/165570

@alexr00 I see in the stack trace that the check for automatic tasks (via getWorkspaceTasks) is leading to this - presumably because the extension’s contributed tasks haven’t yet been registered.

Have you seen this before?
