this problem was since profile's release and not so important number or list of extensions
Importing a profile will not work if you do not have network, as the extensions are installed from Marketplace. But it should not happen when you create the profile. Can you please let us know what do you see when you create the profile?
sad to hear it, such a useful tool for sharing work environment with colleagues as a devops; extensions could be installed from vsix or simple coping between PC's nor than installed from Marketplace. There is at least two different behaviors. First case creating profile: user gets the same 'XHR failed' error, still profile creates and you can switch to it and see it's content almost blank ! ! Second one: user exports default profile to local .code-profile file. In this case import accomplish correct, but when user try to import created profile he gets 'XHR failed' error Such a weird behavior leads to frustration, cose it's seems pretty logical that local profile could be just copied to another PC and imported without any requirements such a internet connection and so on. As for me it's not the obvious behavior
Importing a profile will not work even if you have network:
Are you creating the profile from current profile?
Yep, from default profile
Agreed that creating a profile from a profile that is existing in VS Code should not need network connectivity. But creating a profile from the template needs network connectivity. Because, the template has just extension id and therefore it is required to resolve the id to an extension.
