Windows authentication not working with EPiServer 10 and newest E

Looking forward to build new Intranet-site, I installed EPiServer 10 Alloy sample site with newest Visual Studio templates on Visual Studio 2015/IISExpress. After successful initial setup, I changed the default form-authentication to windows logon-authentication, but site stopped working.

HTTP Error 404.15 - Not Found

The request filtering module is configured to deny a request where the query string is too long.

And the url it creates in browser's address bar looks this:

- For comparison If I installed EPiServer 9 Alloy-site with old EPiServer Visual Studio Template and it worked with windows authentication. I've compared web.config files between both sites but didn't find any significant difference.

Every page I select it tries to redirect me to logon page with following error:

IIS 10.0 Detailed Error - 404.15 - Not Found

Solved the problem. Form-authentication seems to be hardcoded into EPiServer 10:s Alloy Templates. Just commented out lines below comment line "Use cookie authentication" in file StartUp.cs and got it working with windows-authentication.
