Context in Copilot chat is disabled by default in VSCode Insiders

[AdamWr]

Does this issue occur when all extensions are disabled?: It's related to GitHub Copilot Chat extension

• VS Code Version:

Version: 1.101.0-insider (user setup)

• OS Version: Windows 11

Steps to Reproduce:

1. Open VSCode Insiders
2. Open any file with some code
3. Open Chat
4. Ask to explain the code

File context is disabled so it ask to provide a code (in stable build context is enabled by default so it just explain the code).
Also it seems that it's not possible to add specific lines as a context.

Video below, left Insiders, right stable build.

I guess that it might be related to - #243223 and probably this commit - e26c17e (but I'm not sure, just guessing).
So I suppose that it was done intentionally, though I liked an option to select part of the code and ask about it in Copilot Chat.

New version has been released and now it also occurs in stable build.
It seems that there is similar issue - #251409

This seems like a step backwards. Now I have to select the file every time I want it included. And including a section of code requires more steps as well. I prefer the original way this was done of always including this file and the section that was selected.

Happening now with v1.101.1 as well in multiple places :-(

It seems that it has been fixed in the latest Insiders build:
