Opening a notebook in a codespace

1. open a ipynb file in a codespace ->

Issues:

1. ~python extension activation shows the welcome page stealing the focus from the notebook that I opened~ //cc @brettcannon
2. ~I get immediately asked for a survey~
3. the kernel port gets forwarded (this is a missing API adoption, @alexr00 has the details)

@alexr00 sorry i missed ur comment. It was very easy to use (didn’t have to look at any existing code to figure it out).

at we can add to the selector properties so that your provider will get called for fewer ports?

Good question, let me look into this. The problem is these ports are opened by other packages & executables (& in 99% of the case we don’t even know the CLI ahead of time)

@DonJayamanne Yes, for ports that the extension knows about and are internal to the working of the extension, use PortAutoForwardAction.ignore. For ports that the extension doesn’t know about, simple exclude them from your returned array of attributes. If there are any ports that the extension knows about but are external to the working of the extension, i.e. user facing, you can return PortAutoForwardAction.notify if you want to make sure that the user is notified, or you can simply leave them out of your returned array and let the user’s settings handle whether they get notified.
