Currently you can not define extensions per workspace. There is a feature called "profiles" but its not part or combinable with workspaces. (yet?!) This extension tries to solve this issue as good as possible, with notifications like recommendations, because we can't fully automate enabled/disable extensions in the running vscode instance.

This extension was built, after some findings and checking discussions mostly over at: microsoft/vscode#40239 (comment)
And currently there are discussions about profile improvements, regarding missing extension features over here: microsoft/vscode#170916

It could be, that whenever microsoft/vscode#40239 is solved, the extension might not be needed anymore. But it might depend on some specific scenarios, as we are further discussing SemVer handling for extensions as well now.

It also replaces the deprecated extension https://marketplace.visualstudio.com/items?itemName=GARAIOAG.garaio-vscode-unwanted-recommendations
