Hi @fbiryukov_8162,
I did a quick read of the content, and based on this statement ...
"Private Marketplace is available to GitHub Enterprise customers. VS Code users must sign in with a GitHub Enterprise or Copilot Business or Enterprise account to access." sounds to me like a closed ecosystem
And these technical instructions ...
https://github.com/microsoft/vsmarketplace/blob/main/privatemarketplace/latest/README.md#5-connect-vs-code-to-the-private-marketplace
... this is a locked-down / closed ecosystem. There's no published API/specs and no still no support in VSCode for private galleries. They're just "hacking" internal settings to get VSCode to use a different service URL, which they also control.
Obviously this is not something we could/would want to reverse engineer and then support.
If the VSCode team adds support for private repository/galleries (and a public/documented API), and there's some degree of stability to that, we'll consider it. But until then, not much we can do.
Best,
Alex
