How to add project.lock.json file to gitignore

Question

I am trying something like below:

#DNX
project.lock.json

and

*.lock.json

but it does not seem to be ignoring these files.

Answer 1

If file is already tracked to git, then you must first remove it(physically file must be placed out of git folder for the time), commit changes and add the file again to folder. Then git will begin ignoring it using your instruction.
