Answer 1

As Lex Li mentions in a comment:

I said that because I have an extension that does the same (same code from Omnisharp). Ever since VSCode started to auto update extensions, you as an end user might never realize how often an extension has been updated, and each update will trigger a full download of the dependencies (how VSCode works). So your personal feeling/understanding is far from the truth. Like I said, if you disable auto update, then those dependencies will be well cached, and you can update the extension while you have a good connection to download those dependencies again.

I have disabled VSCode auto update of the extensions to avoid it downloading the bits automatically and it's working well.

The Omnisharp repository has the document here . You could pack the platform-specific Omnisharp dependencies to a vsix package, and install it on the target computer offline.
