I am unable to install extensions for VS Code. It worked, than stopped working. I examined the network tab in developer tools from command pallete -> shared process, no errors. I am behind a firewall and proxy at work, but manually installing should work nonetheless.
In install.log I find "One or more extensions are for Visual Studio Code. Try installing them in Visual Studio Code." That is excactly what I have been trying, it seems that VSIX can't understand that this extension is indeed meant for VS Code. Tried many different extensions.
Update after running suggestion from answer: Seems there is a compability issue, just wish this had been shown in the IDE directly.
