Won't install in VSCode

[robinmattern]

When I used the command "Install from VSIX ..." in VSCode, nothing gets installed, nothing happens. When I use the Windows CMD window to run this command:

`code --install-extension .\Installs\VSCode\Extensions\CollapseLevel.vsix`

I get the error below. Would you just have to create a package.json file, or would it be more complicated than that?

Error: extension/package.json not found inside zip.

Hi Robin. This extension is for "Visual Studio", not "Visual Studio Code".
