Steps to reproduce
In VS 2015, create a new website with windows authentication as the authentication method. Run debug with Edge and you will see the popup. Run debug with IE or Chrome and you will see the page auto logs you in.
The windows authentication pop up should not show and the site should auto login with my windows credentials

Thank you for providing this information about the issue. Localhost access can be used to escape browser sandboxes, and so Edge used to block it completely. However, some sites and scenarios required localhost access, and so after careful analysis, we enabled localhost for the Internet app container only. We also special-cased “localhost” as an origin to render in the Internet sandbox so that it could access localhost. A consequence of that is this bug, because WIA (Windows Integrated Authentication) is not supported on the Internet.
A work-around for this is to
1. Enable loopback in the intranet app container as described here https://msdn.microsoft.com/en-us/library/windows/apps/hh780593.aspx?f=255&MSPPError=-2147217396
2. Access your localhost machine by using its fully qualified domain.
