I am using Drupal 8.0.0. I try to add a custom tab page (view page, using views) to my custom content type.
I searched a lot, most sources related to D7 and their instructions not work in D8. It took me a few hours to test tab but tabs not appear in D8.
I also followed the instructions at How to create views tabs in D8? but that didn't work.
By the way, I can get tab by following instruction of https://www.drupal.org/node/2116767, but my question is:how to add tag page (or tab menu) in D8 Views (core version 8.0.0 and above), not by custom module.
