@Bas: Why, the "Visual Studio Extensions for the Windows Library for JavaScript" extension, of course! That's what you said needed updated after all.

I don't recall installing the extension either, so maybe it's an extension installed out of the box like Nuget is, but it's still an extension. If you go to the extension manager it's clearly listed as an installed extension, and does have an uninstall button just asking for you to fix your problem here. Smiley
