Ionic link does not work with Ionic v2

When I run ionic link command inside ionic project folder I got following error message
"You cannot run this command unless you are in an Ionic Project folder"

My system info.

Cordova CLI: 6.3.1
Gulp version: CLI version 1.2.1
Gulp local: Local version 3.9.1
Ionic Framework Version: 2.0.0-beta.11
Ionic CLI Version: 2.0.0-beta.36
Ionic App Lib Version: 2.0.0-beta.19

I used ‘ionic io init’ and setup new app id and then run ionic upload. this solved my issue.
