vs2015 keeps adding project.lock.json to tfs

Question

My folder structure is:

-- Solution folder

--- .tfignore file

--- folder for each project

But vs2015 keeps including my project.lock.json files in source control.

In my .tfignore file, I added: project.lock.json

I've tried undoing and deleting the files from source control.

How can I stop it from including project.lock.json?

Answer 1

As per the link in Patrick-MSFT's answer, this worked for me:

If the changes are "still" in pending changes, first create a backup copy, then make an Undo on them. Close VS, restore the backup copies and then it should work.

The other solution may work, but Visual Studio kept recreating the file as soon as I deleted it, which would immediately add it back to TFs. So I couldn't check in that change. Possibly closing the solution before making the change in the source control explorer, or using the TFS Power Tools shell extension, may work with the other solution.
