BIDS helper - BIML for VS 2015 and sql 2016

I am trying to use BIML for a project - where I need to generate 30-40 similar packages. I think BIML is good choice here to auto generate the packages.

I am using visual studio 2015 and SQL server 2016.

so, for me to accomplish this  need BIDS Helper:

I got the 2016 preview from here : https://bidshelper.codeplex.com/releases/view/621339

after the installation, I think I am supposed to see "BIML FILE" if I right click on the Project Name in SSIS -Solution Explorer.

But I do not see this. BIDS Helper installation was fine.

Whenever I click in the solution explorer, I see this in the output windows from BIDS HELPER

This is confusing. any help appreciated.

Hope it Helps!!
